Merge branch 'drm-armada-devel' of git://git.armlinux.org.uk/~rmk/linux-arm into drm-next

This set of changes migrates Armada DRM from legacy modeset to atomic
modeset.  This is everything from the "Transition Armada DRM planes to
atomic state" and "Finish Armada DRM transition to atomic modeset"
patch sets as posted on drm-devel, excluding the "Finish Armada DRM DT
support" series.

These series did not evoke any comments - if there are any, these can
be addressed via follow up patches.

Developed and tested on Dove Cubox with xf86-video-armada including the
overlay plane, and also tested with the tools in libdrm.
