drm/vc4: hvs: SCALER_DISPBKGND_AUTOHS is only valid on HVS4
The bit used for SCALER_DISPBKGND_AUTOHS in SCALER_DISPBKGNDX
has been repurposed on HVS5 to configure whether a display can
win back-to-back arbitration wins for the COB.
This is not desirable, therefore only select this bit on HVS4,
and explicitly clear it on HVS5.
