Merge branch 'omap/omap2-cleanup' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc into arm/soc

While going through the removal of board files on some other
platforms, I noticed a bit of outdated code on omap2+ that
was left behind after the platform became DT only.

This is a separate branch, to avoid conflicts with other omap2
changes.

* 'omap/omap2-cleanup' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
