[PATCH V2 1/4] PM: wakeup: expose pm_wakeup_pending to modules

[Zhang Rui <rui.zhang@intel.com>]

intel_pch_thermal driver needs a long delay to cool itself (60 seconds
in maximum) during suspend. When a wakeup event occures during the
delay, it is better for the intel_pch_thermal driver to detect this and
quit cooling because the suspend is likely to abort anyway.

Thus expose pm_wakeup_pending to modules so that intel_pch_thermal
driver can be aware of the wakeup events.
