[PATCH 2/5] arm64: dts: meson-g12a: Add AO-CEC-A nodes

[Neil Armstrong]

Amlogic G12A embeds 2 CEC controllers :
- AO-CEC-A the same controller as in GXBB, GXL & GXM SoCs
- AO-CEC-B a new controller

Note, the two controller can work simultanously since 2 Pads can
handle CEC, thus this SoC can handle 2 distinct CEC busses.

This patch adds the nodes for the AO-CEC-A controller until AO-CEC-B
is supported.

Hi Kevin,

The bindings has been reviewed, you can pick the VPU/HDMI bindings with these patches if
you want.

I'll apply the DRM driver patches on the drm-tree directly when reviewed.
