This commit adds the required pin muxing for the network interfaces and
the MDIO interface to be properly initialized. For instance, this makes
it possible for a bootloader to initialize and access the network interfaces

Only the second network interface is pin muxed. The first network interface is
connected to the PHY using SGMII, which uses a dedicated SerDes lane.
