This is true, but all other drivers do the same for GENERIC_PHY at the
moment. If this one gets changed, we should probably apply the same
solution to all current users and fix them consistently.

We can do one of these two:

a) make sure that the framework has 'static inline' stubs that let you
build all drivers using it when the framework itself is disabled.
b) change the drivers using it to 'depends on', and make GENERIC_PHY
itself a hidden option without a Kconfig prompt.

Either solution is probably simple enough that it can be done as
part of this series.
