drm/radeon/kms: display watermark updates (v2)
- Add module option to force the display priority
0 = auto, 1 = normal, 2 = high
- Default to high on r3xx/r4xx/rv515 chips
Fixes flickering problems during heavy acceleration
due to underflow to the display controllers
- Fill in minimal support for RS600
v2 - update display priority when bandwidth is updated
so the user can change the parameter at runtime and it
will take affect on the next modeset.
