net: stmmac: clarify difference between "interface" and "phy_interface"
Clarify the difference between "interface" and "phy_interface" in
struct plat_stmmacenet_data, both by adding a comment, and also
renaming "interface" to be "mac_interface". The difference between
these are:
MAC ----- optional PCS ----- SerDes ----- optional PHY ----- Media
^ ^
mac_interface phy_interface
Note that phylink currently only deals with phy_interface.
