Merge tag 'omap-for-v3.13/display-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

I accidentally removed some mux code for omap4 that I thought was
dead code as omap4 has been booting with device tree only since
v3.10. Turns out I also removed some display related mux code,
so let's revert that except for the dead code parts.
