[Impact]
Screen cannot turn on after screen is off

[Fix]
Below commit from v6.0-rc1 fixes the issue
c577b2f43e80 drm/mgag200: Enable atomic gamma lut update

And applied some other commits to fix the conflicts
c48a36301634 drm/mgag200: Optimize damage clips
3064debaf55e drm/mgag200: Add FB_DAMAGE_CLIPS support
5913ab941d6e drm/mgag200: Acquire I/O lock while reading EDID
931e3f3a0e99 drm/mgag200: Protect concurrent access to I/O registers with lock
e13f13e039dc drm: Add DRM-managed mutex_init()

[Tests]
Verified on the machine with Matrox G200eW3 [102b:0536] graphics card.

[Where problems could occur]
The commits to solve the conflicts are trivial, and not likely to introduce
regressions. The fix patch change a lot of code and hard to evaluate the
risk, but check the latest linus/master tree and linux-next/master tree,
there is no fixed commit for all these cherry-picked commits, so should be
safe to include them.
