drm/msm/mdp5: rip out plane->pending tracking
It would race between userspace thread and commit worker. Ie. vblank
irq would trigger event and userspace could begin the next atomic
update, before the commit worker had a chance to clear the pending
flag.
If we do end up needing something to prevent userspace from trying
another pageflip before getting vblank event, it should probably be
implemented as a pending_planes bitmask, similar to pending_crtcs. See
start_atomic() and end_atomic().
