Merge branch 'drm-sti-next-atomic-2015-08-11' of http://git.linaro.org/people/benjami...

This serie of patches fix minor bugs around how driver sub-components are
bind and planes z-ordering.
The main part is about atomic support: using more atomic helpers allow us
to simplify the code (~300 lines removed) and to ahve a better match between
drm concepts (planes and crtc) and hardware split.

[airlied: fixed up conflict in atomic code]
