net: dsa: mv88e6xxx: pass lane to .serdes_power
Now the first step of all .serdes_power implementations is getting the lane mapping. Since we have an operation for that, call it in the wrapper and pass the lane down to the .serdes_power operation. This also allows to avoid querying the SERDES lane twice in mv88e6xxx_port_set_cmode. At the same time provide mv88e6xxx_serdes_power_{up,down} helpers and prefer up/down instead of on/off as in the documentation.
