PM / wakeirq: Fix typo in prototype for dev_pm_set_dedicated_wake_irq

Looks like I only built test the dev_pm_set_wake_irq and not the
dev_pm_set_dedicated_wake_irq case on x86.

Turns out there's a typo for the dev_pm_set_dedicated_wake_irq
prototype that causes a build error if CONFIG_COMPILE_TEST
and CONFIG_MMC_OMAP_HS are selected.
