Merge tag 'omap-for-v3.20/fixes-not-urgent-pt1' into for-next

Non-urgent fixes for omap variant dm816x that has been in a sorry
broken half merged state for a few years now. This gets us to the
point where we can boot it properly once the related SoC data is
added. Note that we've already made dm816x device tree only by
removing the known broken board file.
