soc/intel/ehl: Add MDIO operation to TSN GbE device

This patch refactors the MDIO access for the TSN GbE device by placing
the MDIO read and write functions into mdio_bus_operations struct which
is assigned to the .ops_mdio member of the PCI device struct. In this
way the MDIO interface of the TSN GbE device is exposed and can be used
by other drivers if needed.
