    drm/i915/fbc: handle dirty rect coords for the first frame
    
    During enabling FBC, for the very first frame, the prepare dirty
    rect routine wouldnt have executed as at that time the plane
    reference in the fbc_state would be NULL. So this could make
    driver program some invalid entries as the damage area. Though
    fbc hw ignores the dirty rect values programmed for the first
    frame after enabling FBC, driver must ensure that valid dirty
    rect coords are programmed. So ensure that for the first frame
    correct dirty rect coords are updated to the HW.
