Kevin Hilman eb350f74eb OMAP3: PM: Enable GPIO module-level wakeups 
Currently, only GPIOs in the wakeup domain (GPIOs in bank 0) are
enabled as wakups.  This patch also enables GPIOs in the PER
powerdomain (banks 2-6) to be used as possible wakeup sources.

In addition, this patch ensures that all GPIO wakeups can wakeup
the MPU using the PM_MPUGRPSEL_<pwrdm> registers.

NOTE: this doesn't enable the individual GPIOs as wakeups, this simply
enables the per-bank wakeups at the powerdomain level.

This problem was discovered by Mike Chan when preventing the CORE
powerdomain from going into retention/off.  When CORE was allowed to
hit retention, GPIO wakeups via IO pad were working fine, but when
CORE remained on, GPIO module-level wakeups were not working properly.

To test, prevent CORE from going inactive/retention/off, thus
preventing the IO chain from being armed:

  # echo 3 > /debug/pm_debug/core_pwrdm/suspend

This ensures that GPIO wakeups happen via module-level wakeups and
not via IO pad.

Tested on 3430SDP using the touchscreen GPIO (gpio 2, in WKUP)
Tested on Zoom2 using the QUART interrup GPIO  (gpio 102, in PER)
