Merge tag 'omap-cleanup-b2-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/cleanup-prcm

Second set of OMAP PRCM cleanups for 3.8.

These patches remove the use of omap_prcm_get_reset_sources() from the
OMAP watchdog driver, and remove mach-omap2/prcm.c and
plat-omap/include/plat/prcm.h.

Basic test logs for this branch on top of Tony's cleanup-prcm branch
at commit 7fc54fd3084457c7f11b9e2e1e3fcd19a3badc33 are here:

    http://www.pwsan.com/omap/testlogs/prcm_cleanup_b_3.8/20121108151646/

However, cleanup-prcm at 7fc54fd3 does not include some fixes
that are needed for a successful test.  With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:

    http://www.pwsan.com/omap/testlogs/TEST_prcm_cleanup_b_3.8/20121108151930/

 which indicate that the series tests cleanly.

This second pull request updates one of the patches which broke
with rmk's allnoconfigs, and also updates the tag description to
indicate that 7fc54fd3 is building cleanly here.
