drm/mgag200: Move mode-config to model-specific code

Move the mode-config code into model-specific code and call the
plane/CRTC helpers as needed. This will help with providing per-
model implementations of individual helpers.

Duplication of the pipeline init function is accepted. Some macros
simplify this for shared helpers.
