Merge tag 'drm-misc-next-2017-03-12' of git://anongit.freedesktop.org/git/drm-misc into drm-next

More drm-misc stuff for 4.12:

- drm_platform removal from Laurent
- more dw-hdmi bridge driver updates (Laurent, Kieran, Neil)
- more header cleanup and documentation
- more drm_debugs_remove_files removal (Noralf)
- minor qxl updates (Gerd)
- edp crc support in helper + analogix_dp (Tomeu) for more igt
  testing!
- old/new iterator roll-out (Maarten)
- new bridge drivers: lvds (Laurent), megachips-something (Peter
  Senna)
