[PATCH v3 3/4] drm/imx: don't wait for vblank and stop calling cleanup_planes in commit_tail

[Philipp Zabel]

drm_atomic_helper_cleanup_planes only calls the cleanup_fb plane
helpers, which we don't implement as a CMA framebuffer based driver.
There is no reason to wait for vblanks in commit_tail only to do nothing
afterwards.

Changes since v2:
 - New patch that removes wait_for_vblanks and cleanup_planes instead
   of reordering commit_hw_done and wait_for_vblanks.
