The mdp5 drm/kms driver currently does not work on command-mode DSI panels due to 'vblank wait timed out' errors. This causes a latency of seconds, or tens of seconds in some cases, before content is shown on the panel. This hardware does not have the something that we can use as a frame counter available when running in command mode, so we need to fall back to using timestamps by setting the max_vblank_count to zero. This can be done on a per-CRTC basis, so the convert mdp5 to use drm_crtc_set_max_vblank_count(). This change was tested on a LG Nexus 5 (hammerhead) phone.
