Is this supposed to be set by the user? If so it should be
CONFIG_CORTINA_PHY_ADDR1
Same goes for the other 3 below.

It is peculiar to have this code here in the case that none of
CONFIG_CORTINA_PHY_ADDR* are defined. Perhaps you should have a
pre-compiler test to ensure at least one is defined.

I don't quite understand this comment and the code that follows. I thought
this whole driver was just for the cortina phy. Why do you have code for
handling some other case in here? Maybe I'mm just being confused by
unclear variable names.
