With LAN8742, LAN8720, LAN83825 and DP83848 as possible options, and the
symbols PHY_LAN8720, PHY_LAN8742, PHY_DP83825 and PHY_DP8348. The default
is PHY_LAN8742 which is the existing behaviour.
The eth_init() parameters for the Portenta H7 board are set to phy_addr=0
and phy_type=LAN8742, which matches the previous defaults and the
schematics.
Tested with LAN8720 and DP83848 breakout boards at 10M Duplex and 100M
Duplex modes.
