Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic AO-CEC controller over to a YAML schemas.

Add AO-CEC compatible string for the Amlogic SM1 SoC family,
a derivate of the G12A AO-CECB controller.

The Amlogic G12A embeds a second CEC controller named AO-CEC-B, and
the other one is AO-CEC-A described by the current bindings.
The register interface is very close but the internal architecture
is totally different.
The other difference is the clock source, the AO-CEC-B takes the
"oscin", the Always-On Oscillator clock, as input and embeds a
dual-divider clock divider to provide the precise 32768Hz base
clock for CEC communication.
