drm/i915: DRRS calls based on frontbuffer
Calls have been added to invalidate/flush DRRS whenever invalidate/flush is
called as part of frontbuffer tracking.
Apart from calls as a result of GEM tracking to fb invalidate/flush, a
call has been added to invalidate fb obj from crtc_page_flip as well. This
is to track busyness through flip calls.
The call to fb_obj_invalidate (in flip) is placed before queuing flip for this
obj.
drrs_invalidate() and drrs_flush() check for drrs.dp which would be NULL if
it was setup in drrs_enable(). This covers for the condition when DRRS is
not supported.
v2: Removing the call to invalidate_drrs from page_flip.
This has not been tested on Android yet, but, in case DRRS transtions do not
work as expected, check by adding back this call in page_flip.
