[PATCH] irq: fix build error due to missing irq_pm_syscore_resume

[Ian Campbell]

irq_pm_syscore_resume is only available iff CONFIG_PM_SLEEP (kernel/irq/pm.o is
only built if this is true). Move the definition (and the dummy definition)
under that umbrella.

Introduced by the backport of upstream 9bab0b7fbaceec47d32db51cd9e59c82fb071f5a
as 0f12a6ad9fa3a03f2bcee36c9cb704821e244c40.
