SGMII 2500 as supported on NXP SoCs requires AN to be disabled, handle
this case in the enetc sgmii init code.

Ethernet interfaces using serial protocols go through the serdes block
integrated in the SoC. This is accessed over dedicated internal MDIOs
which are part of the Ethernet PCI functions. Set up serdes at _start,
along with other protocol specific port/MAC configuration.
MDIO code is shared with enetc_mdio, read/write functions are exported
from fsl_enetc_mdio for this reason.

Adds a driver for the MDIO interface currently integrated in LS1028A SoC.
This MDIO interface is shared by multiple ethernet interfaces and is
presented as a stand-alone PCI function on the SoC ECAM.
Ethernet has a functional dependency on MDIO, for simplicity there is a
single config option for both.

Adds a driver for NXP ENETC ethernet controller currently integrated in
LS1028A. ENETC is a fairly straight-forward BD ring device and interfaces
are presented as PCI EPs on the SoC ECAM.
