Ezequiel Garcia fea038ed55 ARM: mvebu: Add proper pin muxing on the Armada 370 DB board
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
