pm_idle() was that common declaration - but it had the side effect that
it was defined to be called with interrupts disabled, but return with
interrupts enabled.
arm_pm_idle() "fixed" that weirdness such that it's now expected to
return with IRQs in the same state that it was called.
pm_power_off() is a cross-arch hook already.
