Adding support for the Microsoft Surface 3 (non-pro) Type Cover.
The existing definitions and quirks are actually for the Surface
Pro 3 type covers. I've renamed the old constants to reflect that
they belong to the Surface Pro 3, and added a new constant and
matching code for the Surface 3.

The HID_DG_WIDTH and HID_DG_HEIGHT usages report with width and height of
contacts. From this information, a crude determination of orientation is
also possible. This patch reports all three to userspace if a device
reports this usage.

The reports sent from some touch devices (e.g. the Cintiq 24HDT) contain
junk data in the contact slots which follow the final "valid" contact.
To avoid forwarding it to usrspace, we store the reported contact count
during the pre-process phase and then only process that many contacts.
If a device sends its contacts across multiple reports (what Microsoft
refers to as "hybrid" mode) then the contact count will be zero for
reports other than the first.

In some cases, we need access to information before it becomes available
to the 'event' handler. In particular, for some devices we cannot properly
process the finger data without first knowing the "contact count" at the
very end of the report (e.g. the Cintiq 24HDT touch screen, when forced
through the GENERIC codepath).
Since the HID subsystem doesn't provide a way to take action before 'event'
is called, we take a cue from hid-multitouch.c and add a pre-process step
within the 'report' handler that performs the same function.

A firmware bug in some touchpads causes the F01 interrupt enable register
to be cleared on reset. This register controls which RMI functions generate
interrupts and when it is cleared, the touchpad stops reporting all data.
This patch looks for the cleared F01 control register and writes the
correct value based on interrupt mask computed while scanning the PDT.

Allocated input devices should not use the 'pen_name' by default since
we do not know at that point in time if that is an appropriate choice
of name. Instead, use the (tool-agnostic) name that is stored in the
device's 'wacom_features' structure. This also has the nice side-effect
of requring us to be explicit about the naming of the pen device, as
we already are for touch and pad devices.

The 'wacom_allocate_inputs' function tries to allocate three input devices: one
each for the pen, touch, and pad. The pointers that are returned by the
'wacom_allocate_input' calls are temporarily stored to local variables where
they are checked to ensure they're non-null before storing them in the
'wacom_wac' structure. If an allocation fails, the 'wacom_free_inputs'
function is called to reclaim the memory. Unfortunately, 'wacom_free_inputs' is
called prior to the pointers being copied, so it is not actually able to free
anything.
This patch has the calls to 'wacom_allocate_input' store the pointer directly
in the 'wacom_wac' structure where they can be freed. Also, it replaces the
call to 'wacom_free_inputs' with the (more general) 'wacom_clean_inputs' and
removes the no-longer-used function.

As mentioned in the comment in the code, both the pen and touch data
come from the interface tagged as BAMBOO_PAD. The driver re-routes the
events for the Pen to the generic HID interface and keeps the ones for
the touch through this current interface.
Clearing the WACOM_DEVICETYPE_PEN bit removes the extra unused interface
added in 2a6cdbd ("HID: wacom: Introduce new 'touch_input' device") and
makes the Bamboo PAD to behave like in 4.1.

cp2112_i2c_xfer() only supports a single i2c_msg. More than
one message at a time just returns EIO. This breaks certain
important cases. For example, the at24 eeprom driver generates
paired write and read messages (for eeprom address and data).
Since the device doesn't support i2c repeated starts in general,
but does support a single write-repeated-start-read pair
(since hardware rev 1), we recognize the latter case and
implement only that.

i2c-hid takes care of requesting and handling IRQs for HID devices
which in turns might expect them to be always active when working
in normal conditions. Hence, disabling IRQs before calling the suspend
callbacks can potentially cause problems since device drivers might
try to perform operations needing them.
Fix this by disabling IRQs only after the suspend callbacks had been
executed.

Current implementation of cp2112_raw_event() only accepts one data report at a
time. If last received data report is not fully handled yet, a new incoming
data report will overwrite it. In such case we don't guaranteed to propagate
the correct incoming data.
The trivial fix implemented here forces a single report at a time by requesting
in cp2112_read() no more than 61 byte of data, which is the payload size of a
single data report.

Historically, both the touch and pad tools would have shared the
'BTN_TOOL_FINGER' type. Any time you needed to distinguish the two, you
had to use some other bit of knowledge (e.g. that the pad was on the same
interface as the pen, and thus 'touch_max' would be zero).
To make these checks more readable, we introduce WACOM_DEVICETYPE_PAD.
Although we still have to rely on other bits of knowledge to set this
bit on the right interface (since it cannot be detected from the HID
descriptor), it can be done just once inside 'wacom_setup_device_quirks'.
This patch introduces no functional changes.

The USB devices that this driver has historically supported segregate the
pen and touch portions of the tablet. Oftentimes the segregation would be
done at the interface level, though on occasion (e.g. Cintiq 24HDT) the
tablet would combine two totally independent USB devices behind an internal
USB hub. Because pen and touch never shared the same interface, it made
sense for the 'device_type' to store a single value: "pen" or "touch".
Recently, however, some I2C devices have been created which combine the
two. A first step to accomodating this is to expand 'device_type' so that
it can represent two (or potentially more) types simultaneously. To do
this, we treat it as a bitfield and set/check individual bits rather
than using the '=' and '==' operators.
This should not result in any functional change since no supported devices
(that I'm aware of, at least) have HID descriptors that indicate both
pen and touch reports on a single interface.

The HID device does not need to know about the ACPI device associated with
the underlying i2c device. Setting the ACPI companion field in the HID device
also has the side effect of causing HID to be set as wake capable, since
acpi_bind_one uses's the companion ACPI device's wakeup flags to set the
device as wake capable. Which results in power/wakeup files in sysfs for
the HID device which do not do anything.
