Export log_suspend_abort_reason and log_abnormal_wakeup_reason. This
will allow device-specific vendor modules to log these specific wakeup
reasons.

make sure that only one of the following wakeup reasons being captured:
1. RESUME_IRQ: system has suspended successfully and wakeup by IRQs.
2. RESUME_ABORT: wakeup sources are activated during suspend flow.
3. RESUME_ABNORMAL: misconfigured IRQ being captured.

The 0-day test bot found three minor issues in the wakeup_reason
enhancements patch, including two undeclared functions that should have
been static, an allegedly uninitialized pointer (which is actually set
in the line immediately prior to cppcheck's complaint), and a type
mismatch when printing timespec64 fields on a 32-bit build.
These changes address those findings.

These changes build upon the existing Android kernel wakeup reason code
to:
* improve the positioning of suspend abort logging calls in suspend flow
* add logging of abnormal wakeup reasons like unexpected HW IRQs and
IRQs configured as both wake-enabled and no-suspend
* add support for capturing deferred-processing threaded nested IRQs as
wakeup reasons rather than their synchronously-processed parents
