Yes it is, however I thought it could be fine keeping it set explicitely
anyway, as we do have a PCS on that bus and we don't want any autoscan
happening. Since these two drivers are the first users of mdio_regmap,
my hope is that we could get these reference usages covering all fields.

Should I drop this ?
