drm/meson: move OSD scaler management into plane atomic update 

In preparation to support the Primary Plane scaling, move the basic
OSD Interlace-Only scaler setup code into the primary plane atomic
update callback and handle the vsync scaler update like the overlay
plane scaling registers update.
