[edk2] [platforms PATCH 19/25] Marvell/Drivers: MvBoardDesc: Extend protocol with MDIO support

[Marcin Wojtas]

Introduce new callback that can provide information
about MDIO controllers to the Mdio driver.

Extend ArmadaBoardDescLib with new structure MV_BOARD_MDIO_DESC,
for holding board specific data.
