Hans de Goede e30a21c6fe platform/x86: intel_int0002_vgpio: Use acpi_register_wakeup_handler()

commit 767191db82 upstream.

The Power Management Events (PMEs) the INT0002 driver listens for get
signalled by the Power Management Controller (PMC) using the same IRQ
as used for the ACPI SCI.

Since commit fdde0ff859 ("ACPI: PM: s2idle: Prevent spurious SCIs from
waking up the system") the SCI triggering, without there being a wakeup
cause recognized by the ACPI sleep code, will no longer wakeup the system.

This breaks PMEs / wakeups signalled to the INT0002 driver, the system
never leaves the s2idle_loop() now.

Use acpi_register_wakeup_handler() to register a function which checks
the GPE0a_STS register for a PME and trigger a wakeup when a PME has
been signalled.
