[PATCH 05/11] drm/meson: Add G12A support for OSD1 Plane

[Neil Armstrong]

Amlogic G12A SoC supports now up to 3 OSD planes (1 more than the
previous SoCs) and a brand new OSD plane blender module.

This patch uses the same OSD1 plane G12A, using the exact same scaler
and OSD1 setup registers, except using the new blender register to
disable the plane.
