From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>
This commit changs some functions to operate on intel_crtc_state rather
than the base CRTC objects in order to transit to atomic. The reason we
want to do this is to allow future patches to move the computation steps
into the atomic 'check' phase where they'll be operating on in-flight CRTC
states rather than already-committed states.
v2: make the change for vlv_compute_wm_level() which is forgotten in v1
