[PATCH v2 1/5] dt-bindings: phy: ti,tcan104x-can: Document NXP TJA1051/1048

[Peng Fan]

The TJA1051 is a high-speed CAN transceiver which is a pin-compatible
alternative for TI TCAN1043 with Sleep mode supported, and has a compatible
programming model, therefore use ti,tcan1043 as fallback compatible.

The TJA1048 is a dual high-speed CAN transceiver with Sleep mode supported.
