Merge branch 'drm-fixes-4.18' of git://people.freedesktop.org/~agd5f/linux into drm-fixes

A few display and GPUVM fixes for 4.18.

A few more fixes for 4.18. Two display fixes and a fix to avoid a segfault if
the GPU does not power up properly on resume.  These are on top of my pull
from earlier this week.
