dt-bindings: can: renesas,rcar-canfd: Add transceiver support 

Add support for describing CAN transceivers as PHYs.

While simple CAN transceivers can do without, this is needed for CAN
transceivers like NXP TJR1443 that need a configuration step (like
pulling standby or enable lines), and/or impose a bitrate limit.
