drm/mgag200: Provide per-device callbacks for BMC synchronization
Move the BMC-related code into its own file and wire it up with device
callbacks.
While programming a new display mode, G200EW3 and G200WB have to de-
synchronize with the BMC. Synchronization is done via VIDRST pins
and controlled via VRSTEN and HRSTEN bits. Move the BMC code behind
a serviceable interface and call it from the CRTC's enable and
disable functions.
