Merge tag 'omap-for-v3.16/prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

Merge "ARM: omap prcm changes for v3.16 merge window" from Tony Lindgren:

PRCM changes for omaps. I ended up merging these with the
big endian changes because of the merge conflicts for read
and write operations. Via Paul Walmsley <paul@pwsan.com>:

Some OMAP PRCM cleanup patches.  These help prepare to convert the PRCM
code into drivers.

Basic build, boot, and PM test results are available here:
