Here are some CPUidle/Suspend cleanup patches done by adding
some more functionality in the OMAP Powerdomain framework.
They mostly cleanup OMAP3 but the same ideas can be used/
applied for OMAP4 and beyond.

The series is based off Teros' series [1] to add usecounting
support within the OMAP Powerdomain framework.

The patches are tested with RET/OFF in CPUidle and Suspend
on 3630 beagle Xm and 3430 SDP.
