Subject: [PATCH 2/3] dt-bindings: usb: atmel: Add Microchip LAN966x compatible string

The USB device controller available in the Microchip LAN966x SOC
is the same IP as the one present in the SAMA5D3 SOC.

Add the LAN966x compatible string and set the SAMA5D3 compatible
string as a fallback for the LAN966x.
