    drm/i915: Add .get_hw_state() method for planes · 51f5a096
    Ville Syrjälä authored
    Add a .get_hw_state() method for planes, returning true or false
    depending on whether the plane is enabled. Use it to rewrite the
    plane enabled/disabled asserts in platform agnostic fashion.
    
    We do lose the pre-gen4 plane<->pipe mapping checks, but since we're
    supposed sanitize that anyway it doesn't really matter.
    
    v2: Reoder patches to not depend on enum old_plane_id
        Just call assert_plane_disabled() from assert_planes_disabled()
    v3: Deal with disabled power wells in .get_hw_state()
    v4: Rebase due skl primary plane code removal
