[PATCH] dt-bindings: i2c: meson: convert to yaml

[PATCH] dt-bindings: i2c: meson: convert to yaml

[Neil Armstrong]

Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic I2C Controller over to YAML schemas.

I need an ack from Beniamino for this.

Also, do you want to maintain only this file or also the driver? The
latter would be much appreciated, of course!

I'm taking responsibility for the bindings to make sure the DT is correct,
but I don't have time to maintain this driver for the moment, sorry,
