[PATCH 3/3] gpio: omap: Get rid of pm_runtime_irq_safe()

[Tony Lindgren <tony@atomide.com>]

If a gpio instance has any GPIO bits requested we do a pm_runtime_get()
on the device. Now with cpu_pm handling the deeper SoC idle state quirks,
let's just remove pm_runtime_irq_safe() call and add a warning in case we
ever happen to encounter it.
