msm_fb: display: fix the hang issue caused by solidfill pipe

When mdp pipe solidfill mode is disabled, the staled pipe info is used
to update mdp pipe regs. This caused mdp hang. Since
mdp4_overlay_rgb_setup function already resets solidfill mode, this
patch removes any pipe register updates that are related to disabling
solidfill mode.
