ENGR00304563-1 net: fec: add fixed phy address support
Add fixed phy address support.
i.MX6sx has two MACs, and MAC1 mdio bus connects to two phys which
means MAC2 share MDIO bus with MAC1. So for any one of the two MACn,
which can scan two phy address. For current implementment, it selects
the little address for the default address and binding with the phy.
For the situation, user can add the fixed phy address to DTS.
