net: mdio-uclass: introduce dm_eth_phy_connect_interface()

Browse Source 
dm_eth_phy_connect_interface() is a variant of dm_eth_phy_connect() that
allows to set the used PHY mode, in case the MAC driver needs to fix it
up. The previously static dm_eth_connect_phy_handle() is renamed and
extended for this purpose.
