some time ago I thought it was smart to add a compatible string with the PHY ID.
this was until I figured out that it should only be done if the PHY
reports an invalid ID: [0]
that's why most .dts files that I've touched skip the "compatible"
property and use a comment like "/* Realtek RTL8211F (0x001cc916) */"
instead
