Migration to DM_ETH is mandatory, so convert mx6cuboxi to Ethernet
Driver Model.

This also brings the benefit of restoring Ethernet functionality.

Do we still need this header?

The definitions of these ENET_PAD_CTRL* macros can go away as well.

relevant feedback, I figured I could as well:
Does this board make any use of DM_MDIO? Doesn't look like it.
