dt-bindings: phy: add support for NXPs TJA1145 CAN transceiver

Adding documentation for NXPs TJA1145 CAN transceiver, which resides like
the ti,tcan104x-can.yaml in the same directory as other generic PHY
subsystem bindings. At the moment there is only support for simple PHYs
by using regulator bindings in combination with can-transceiver.yaml or
PHYs that implement the generic PHY subsystem like the NXP TJA1145.
