net: dsa: mv88e6xxx: Fix 6095/6097/6185 ports in non-SERDES CMODE
The .serdes_get_lane op used the magic value 0xff to indicate a valid
SERDES lane and 0 signaled that a non-SERDES mode was set on the port.
Unfortunately, "0" is also a valid lane ID, so even when these ports
where configured to e.g. RGMII the driver would set them up as SERDES
ports.
- Replace 0xff with 0 to indicate a valid lane ID. The number is on
the one hand just as arbitrary, but it is at least the first valid one
and therefore less of a surprise.
- Follow the other .serdes_get_lane implementations and return -ENODEV
in the case where no SERDES is assigned to the port.
