Now that we have the DT validation in place, let's convert the device tree
bindings for the TI SoC Davinci/OMAP/Keystone2 MDIO Controllerr over to a
YAML schemas.

This my first attempt to work with YAML schemas, hence RFC.

No problems validating this schema, but the example in mdio.yaml isn't 
happy:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/net/mdio.example.dt.yaml: 
mdio@5c030000: 'bus_freq' is a required property

Convert implies deleting the old binding...
