Define two new "compatible" values for Ethernet PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45" are used to indicate a PHY uses the corresponding protocol.
If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we indicate this so that get_phy_device() can properly probe the device.
