====================
mv88e6xxx fixed link fixes

Recent changes for how the MAC is configured broke fixed links, as
used by CPU/DSA ports, and for SFPs when phylink cannot be used. The
first fix is unchanged from v1. The second fix takes a different
solution than v1. If a CPU or DSA port is known to have a PHYLINK
instance, configure the port down before instantiating the PHYLINK, so
it is in the down state as expected by PHYLINK.
