We also need to call the frontbuffer flip to trigger proper invalidations when disabling planes. Otherwise we will miss screen updates when disabling sprites or cursor. On core platforms where HW tracking also works, this issue is totally masked because HW tracking triggers PSR exit however on VLV/CHV that has only SW tracking we miss screen updates when disabling planes. It was caught with kms_psr_sink_crc sprite_plane_onoff and cursor_plane_onoff subtests running on VLV/CHV. This is probably a regression since I can also get this with the manual test case, but with so many changes on atomic modeset I couldn't track exactly when this was introduced.
