Ethernet PHY on lane 1 also uses zero +port number. + +So construct "port" bits for SMC call argument can be constructed directly +from PHY type and lane number. + +Change driver code to always pass zero port number for non-ethernet PHYs +and for ethernet PHYs determinate port number from lane number. This +simplifies the driver. + +As port number from DT PHY configuration is not used anymore, remove whole +driver code which parses it.
