net: macb: add support for 1000BASE-X autonegotiation to PCS
The current PCS code unconditionally uses SGMII autonegotiation, though
the hardware supports both SGMII and 1000BASE-X modes. Decouple the
choice of PCS enablement from use of the SGMII mode when running at
gigabit rates and announce to phylink that 1000BASE-X is a supported
operating mode. This enables direct attachment of the PCS to e.g. an
SFP.
The 1000BASE-X code in phylink also sometimes calls the autonegotiation
restart method, so add an implementation of autonegotiation restart and
make sure that pcs_config() signals to phylink when the AN advertisement
has changed.
