The mode-setting pipeline can disabled damage clippings for a commit
by setting ignore_damage_clips in struct drm_plane_state. The commit
will then do a full display update.
Test the flag in the primary ldu plane's atomic_update and do a full
update if it has been set.
Commit 35ed38d58257 ("drm: Allow drivers to indicate the damage helpers
to ignore damage clips") introduced ignore_damage_clips to selectively
ignore damage clipping in certain framebuffer changes. Vmwgfx does not
do that, but DRM's damage iterator will soon rely on the flag. Therefore
supporting it here as well make sense for consistency.
