This change passes DRM_PLANE_COMMIT_ACTIVE_ONLY during
drm_atomic_helper_commit_planes in complete commit. Passing
this flag insures that if crtc is inactive, plane update
will not be made. This avoids trying to commit a plane
while entering low power mode when crtc and encoder are
already disabled.

When plane is detached from crtc in one atomic commit and then
attached to another crtc in the next atomic commit, the second
plane state swap will happen when the first commit is still running
in the previous crtc's worker thread, which will result in two
threads programming the same plane and run into undeterministic
state.
Fix is to add plane_mask check before state swap, together with
crtc_mask check. This will make sure there is no pending worker
thread working on the same plane.

Since other driver module could not use msm_drm function,
then the notify function was moved to drm_panel. So used
the new drm_panel notify API instead of the old one.

Remove unnecessary vblank get and put. This call is
not required before calling wait for crtc commit done
because downstream driver has its own vblank refcount.
Without this change vblank enable call is seen every
vsync.

This change adds support for dynamic switching of dsi clocks
to avoid RF interference issues. Also with dynamic dsi clock
switch feature coming into picture, now populate the supported
refresh rate as list instead of providing a range. Modify the
logic to enumerate all the modes in dsi driver, taking dynamic
bit clocks, resolutions and refresh rates into account.

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.
