disp: msm: Add support for seamless panel operating mode switch

Selaa lähdekoodia 
DSI display may support video mode and command mode both and it may
support transition between these two modes.
This change adds seamless transition between these two modes for DSI
display by avoiding crtc enable/disable and panel power on/off
during modeset.
