dt-bindings: can: xilinx_can: Document phys property

Browse Source 
The Xilinx CAN and CANFD controllers can be connected to an external
CAN transceiver on the board. That connection is described with the
standard "phys" property on the controller node, pointing to a CAN
transceiver PHY node which models the transceiver and its control
lines (for example the standby/enable signals).

Describe the optional "phys" property (a single transceiver PHY) so
the on-board CAN transceiver can be described in the device tree.
