lantiq: kernel 4.14: autoselect matching vr9 rev firmware
Add a custom xrx200 ethernet phy compatible to load the firmware matching the vr9 revision without specifing an expected revision. We have quite a few boards in the tree were later produced ones are using a more recent vr9. It is impossible to distinguish which revision of the vr9 is used without opening the case and removing a heatsink for some of them. Signed-off-by: Mathias Kresin <dev@kresin.me>
