Subject: [PATCH] drm/ast: Program mode for AST DP in atomic_mode_set
The CRTC's atomic_flush function contains code to program the
display mode to the AST DP chip. Move the code to the encoder's
atomic_mode_set callback. The DRM atomic-modesetting code invoke
this callback as part of the atomic commit.
v2:
- fix typos in commit message
