[0/4] net: dsa: mv88e6xxx: serdes link without phy

This small series gets my hardware into a working state. The key points are to
make sure we don't force the link and that we ask the MAC for the link status.
I also have updated my dts to say `phy-mode = "1000base-x";` and `managed =
"in-band-status";`

I've included patch #4 in this series but I don't have anything to test it on.
It's just a guess based on the datasheets. I'd suggest applying patch 1, 2 & 3
and leaving 4 for the mailing list archives.
