drm/msm: update rsc state machine for cmd and vid state

RSC command and video state switch only wait for vsync
when they toggle between each other. However, command mode
needs a vsync wait for each configuration update. For ex:
inline rotation start, inline rotation end, etc. Similar
vsync wait can be avoided on video mode because there is
no sequence running. Rsc state machine update is required
to account for these configuration changes.
