Prep changes for state based resource management.
Moves all the hw block tracking for the crtc to the state object.
changes in v4: - Serialize crtc state access in debugfs handlers (Sean) - Split the crtc width query as a separate change (Sean) changes in v5: - mode set lock all before crtc state access (Sean) - remove unwanted memset for hw mixer cache (Sean) changes in v6: - none
