Christian Hewitt 081893e254 drm/meson: fix 1px pink line on GXM when scaling video overlay 
[ Upstream commit 5c8cf1664f288098a971a1d1e65716a2b6a279e1 ]

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.
