msm_fb: display: switch mdp mode without turning off timing generator
MDP need to be in idle state before switching to different mode.
Dmap_done interrupt is delivered when the last line of frame is
clocked out. Therefore mdp is in idle state during dmap_done ISR.
This patch execute mdp mode switching inside dmap_done ISR.
Therefore timing generator is not necessary to be turned off
since mdp is in idle state already.
