Register each CAN channel of the device as an devlink physical port.
This makes it easier to get device information for a given network
interface (i.e. can2).

Example output:
 $ devlink dev
 usb/1-1.3:1.0

 $ devlink port
 usb/1-1.3:1.0/0: type eth netdev can0 flavour physical port 0 splittable false
 usb/1-1.3:1.0/1: type eth netdev can1 flavour physical port 1 splittable false

 $ devlink port show can1
 usb/1-1.3:1.0/1: type eth netdev can1 flavour physical port 0 splittable false

Looks fine to me. Out of curiosity, do you have some plans to extend use
of devlink port in the future, or this is it?
