Subject: [PATCH 1/3] PM / Sleep: Add macro to define common noirq system PM callbacks

From: Grygorii Strashko <Grygorii.Strashko@...aro.org>

The same approach is used as for the existing SET_SYSTEM_SLEEP_PM_OPS,
but for noirq callbacks.

New SET_NOIRQ_SYSTEM_SLEEP_PM_OPS, defined for CONFIG_PM_SLEEP, will
point ->suspend_noirq, ->freeze_noirq and ->poweroff_noirq to the same
function. Vice versa happens for ->resume_noirq, ->thaw_noirq and
->restore_noirq.
