drm/msm/sde: reset clt path after timing engine disabled

For MDP rev 5.0, CTL path reset is required after timing engine
is disabled for video mode interface. The reset includes 3d_merge,
active_intf, layer mixer and ctl path after timing engine is
disabled. This reset call does not need to wait for vsync because
timing engine is already disabled. It may lead to continuous underrun
if reset sequence is not followed and same ctl path is used for
different resolution display.
