[PATCH 1/2] dt-bindings: usb: ite,it8851: Add IT5271 series support

[Amber Kao]

Add compatible strings for the ITE IT5271 series USB Type-C Power
Delivery controllers. The IT5272 and IT5274 are the two-port variants,
and the IT5273 and IT5274 additionally support EPR (Extended Power
Range). All of them share the IT5271 programming interface.
