Now that the generic IRQ and GPIO frameworks are used for enabling and
disabling GPIO IRQ wakeup sources, there is no longer a need to call
[enable|disable]_irq_wake() in the low-level code. Doing so results
in recursive calls to [enable|disable]_irq_wake().
This was discovered in the suspend/resume path on OMAP3/Beagle using
the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the
suspend/resume path.
