drm/mgag200: Convert to simple KMS helper

Browse source

The mgag200 supports a single pipeline with only a primary plane. It can
be converted to simple KMS helpers. This also adds support for atomic
modesetting. Wayland compositors, which use pageflip ioctls, can now be
used with mgag200.

v2:
	* prepare encoder and CRTC in a separate patch
	* remove suspend/resume code in a separate patch
	* don't call set_format_regs() in pipe_update()
