Variable trip is assigned but never read, hence it is redundant
and can be removed. Cleans up clang warning:
drivers/thermal/intel_bxt_pmic_thermal.c:204:4: warning: Value stored
to 'trip' is never read

Since all second level thermal IRQs are consumed by the same
device(bxt_wcove_thermal), there is no need to expose them as separate
interrupts. We can just export only the first level IRQs for thermal and
let the device(bxt_wcove_thermal) driver handle the second level IRQs
based on thermal interrupt status register. Also, just using only the
first level IRQ will eliminate the bug involved in requesting only the
second level IRQ and not explicitly enable the first level IRQ. For
more info on this issue please read the details at,
https://lkml.org/lkml/2017/2/27/148
This patch also makes relevant change in bxt_wcove_thermal driver to use
only first level PMIC thermal IRQ.

Added one additional parameter to thermal_zone_device_update() to provide
caller with an optional capability to specify reason.
Currently this event is used by user space governor to trigger different
processing based on event code. Also it saves an additional call to read
temperature when the event is received.
The following events are cuurently defined:
- Unspecified event
- New temperature sample
- Trip point violated
- Trip point changed
- thermal device up and down
- thermal device power capability changed

This change adds support for Intel BXT Whiskey Cove PMIC thermal
driver which is intended to handle the alert interrupts triggered
upon thermal trip point cross and notify the thermal framework
appropriately with the zone, temp, crossed trip and event details.
