Amlogic G12A SoC supports the same set of Video Planes, but now
are handled by the new OSD plane blender module.
This patch uses the same VD1 plane for G12A, using the exact same scaler
and VD1 setup registers, except using the new blender register to
disable the plane.

Now that the DMC register range is no longer in the bindings, remove any
mention towards it and exclusively use the meson-canvas module.

The Amlogic Meson GX SoCs support an Overlay plane behind the primary
plane for video rendering.
This Overlay plane support various YUV layouts :
- YUYV
- NV12 / NV21
- YUV444 / 422 / 420 / 411 / 410
The scaler supports a wide range of scaling ratios, but for simplicity,
plane atomic check limits the scaling from x5 to /5 in vertical and
horizontal scaling.
The z-order is fixed and always behind the primary plane and cannot be changed.
The scaling parameter algorithm was taken from the Amlogic vendor kernel
code and rewritten to match the atomic universal plane requirements.
The video rendering using this overlay plane support has been tested using
the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem
Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.
