I guess you could drop that rk3399 mention instead make the
driver complain? Trying to keep that list up to date will get hard
and I guess the other socs may very well hide that setting somewhere
in their undocumented phy registers as well.

I guess a bit of alphabetical ordering might also be nice,
rockchip,force-bvalid above rockchip,utmi-avalid
Makes it easier to read ;-)
