Subject: [PATCH RFC v2 2/6] drm: msm: add dirty framebuffer helper

Use drm_atomic_helper_dirtyfb() as the dirty callback in the
msm_framebuffer_funcs struct. Call drm_plane_enable_fb_damage_clips()
when the planes are initialized in mdp4, mdp5, and dpu1.

Signed-off-by: Brian Masney <masneyb@...tation.org>

Changes since v1:
- Add drm_plane_enable_fb_damage_clips() to plane init for mdp4, mdp5,
  and dpu1.
