[PATCH v2 1/2] dt-bindings: phy: ti, tcan104x-can: Document mux-states property

[Aswath Govindraju]

On some boards, for routing CAN signals from controller to transceivers,
muxes might need to be set. This can be implemented using mux-states
property. Therefore, document the same in the respective bindings.
