drm/ast: Program display mode in CRTC's atomic_enable()
This change simplifies ast's modesetting code. The display mode
is now programmed from within the CRTC's atomic_enable(), which
only runs if we actually want to program the mode.
Corresponding code in atomic_flush() is being removed. Also removed
is atomic_begin(), which serves no purpose at all.
