This doesn't make any sense. You have two *separate* blocks on the
A20, the EMAC and the GMAC, and yet, you want SUN7I_EMAC to not
represent the EMAC found, but the GMAC with an MII phy?

The current configuration we have is fine as it is, there's no need to
change it, especially for something that is so confusing.
