This is causing problem when plane is re-used for another purpose. Fix this by clearing selective fetch area when duplicating plane state. Now as the state is cleared we need to ensure we have consistent selective fetch area in plane state on full update. Earlier this was relying on selective fetch area being copied from old state on state duplicate. Now this isn't true anymore as we are clearing it. Tackle this by setting full plane area as selective fetch area for each plane on full update. Rename the label as skip_su_area_calc as the loop setting the plane selective fetch area is not skipped anymore. Move also psr2_sel_fetch_pipe_state_supported check after psr2_su_area initialization. The loop is run on full update as well now and it needs initialized psr2_su_area. Clip_area_update is only touching rect height and x1/x2 are left untouched. Don't set the area at all for planes not intersecting with the selective update area. It is already zero sized after plane state duplicate.
