[1/6] dt-bindings: phy: meson8b-usb2: Convert to json-schema

Now that we have the DT validation in place, let's convert the device
tree bindings for the Amlogic Meson8, Meson8b, Meson8m2 and GXBB USB2
PHY over to a YAML schema.

While here, also add the fallback compatible string
"amlogic,meson-gxbb-usb2-phy" which is already used in
arch/arm/boot/dts/meson{,8,8b}.dtsi.

Is the kernel now accepting "Tested-by" lines from robots?

If hexdump0815@googlemail.com is not a robot, can you please use
your full legal name instead?

Should we not? bots have been given Reported-by...

Looking at emails, this doesnt seem a bot, so I am asking for full legal
name for these to be added.

Thanks

Needs 2 more spaces indent.
