(was: drm/mgag200: Handle VIDRST from BMC helpers)

The VIDRST pin controls CRTC synchronization with an external clock
chip, such as a BMC or TV encoder. This patchset separates the CRTC
state from the BMC state and streamlines the driver code.

v3:
- don't clear VIDRST bits unnecessarily (Jocelyn)
v2:
- run BMC and VIDRST logic from CRTC code (Jocelyn)

Thomas Zimmermann (3):
  drm/mgag200: Only set VIDRST bits in CRTC modesetting
  drm/mgag200: Remove vidrst callbacks from struct mgag200_device_funcs
  drm/mgag200: Rename BMC vidrst names
