Merge tag 'omap-cleanup-a-for-3.8' of... 

Merge tag 'omap-cleanup-a-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/cleanup-prcm

The first set of OMAP PRM/CM-related cleanup patches for 3.8.
Prepares for the future move of the PRM/CM code to drivers/.  Also
includes some prcm.[ch] cleanup patches from the WDTIMER cleanup
series that don't need external acks.

Basic test logs for this branch on top of v3.7-rc2 are here:

http://www.pwsan.com/omap/testlogs/prcm_cleanup_a_3.8/20121021123719/

But due to the number of unrelated regressions present in v3.7-rc[12],
it's not particularly usable as a testing base.  With reverts, fixes,
and workarounds applied as documented in:

http://www.pwsan.com/omap/testlogs/test_v3.7-rc2/20121020134755/README.txt

the following test logs were obtained:

http://www.pwsan.com/omap/testlogs/prcm_cleanup_a_3.8/20121020231757/

which indicate that the series tests cleanly.
