Merge tag 'drm-misc-next-2017-02-03' of git://anongit.freedesktop.org…

…/git/drm-misc into drm-next

Final 4.11 feature pull request:
- sii8520 bridge update from Andrzej
- ->release callback, maybe somewhen in the future we'll even get
  drm_device lifetimes correct! (Chris Wilson)
- drm_mm search improvements, and good docs for different search
  strategies now (Chris)
- simplify fbdev emulation init parameters (Gabriel)
- bunch of misc things all over

... and the first few patches from our small driver in drm-misc
experiment:
- cleanups for qxl and bochs from a few different people
- dsi support for vc4 (not yet the panel driver, that's under discussion
  still) from Eric
- meson rename to meson-drm to distinguish from other platform drivers
  (Neil Amstrong)
