Merge tag 'omap-for-v3.20/cleanup-pt1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

Merge "omap clean-up for v3.20" from Tony Lindgren:

Clean-up for omaps to remove dead code found with cppcheck after
we've made several SoCs to boot in device tree only mode.
