Merge tag 'omap-for-v3.19/prcm-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

Pull "omap prcm clean-up for v3.19" from Tony Lindgren:

Clean-up series for omap PRCM (Power Reset Clock Module) from
Tero Kristo to move things a bit closer to becoming a proper
device driver.
