drm/meson: fix 1px pink line on GXM when scaling video overlay
Playing media with a resolution smaller than the crtc size requires the
video overlay to be scaled for output and GXM boards display a 1px pink
line on the bottom of the scaled overlay. Comparing with the downstream
vendor driver revealed VPP_DUMMY_DATA not being set [0].
Setting VPP_DUMMY_DATA prevents the 1px pink line from being seen.
