Pull drm updates from Davbe Airlie:
"This is the main pull request for graphics for 5.6. Usual selection of
changes all over.
I've got one outstanding vmwgfx pull that touches mm so kept it
separate until after all of this lands. I'll try and get it to you
soon after this, but it might be early next week (nothing wrong with
code, just my schedule is messy)
This also hits a lot of fbdev drivers with some cleanups.
