Convert the Renesas R-Car Gen2 USB PHY Device Tree binding documentation
to json-schema.
Add missing properties.
Rename the device node from "usb-phy" to "usb-phy-controller", as it
does not represent a USB PHY itself, and thus does not have a
"#phy-cells" property.
Rename the child nodes from "usb-channel" to "usb-phy", as these do
represent USB PHYs.
Drop the second example, as it doesn't add any value.
