Agreed. It just seemed "cleaner" to me to set config_pre_init in
separate probe functions which are pretty straightforward and short.
Thus not complexifying an already-not-so-straightforward config_init
function.

Anyway, I'll use the phy_id as suggested so that we don't overload the
vsc8531_private structure (since it's also only called once, in
config_init).

Thanks,
Quentin
