Might I suggest that you not eliminate the whole driver?  If you leave
just this part (and the init stuff below it), and convert the
config_aneg and read_status pointers to use the genphy versions, the
kernel will, at least, be able to report what type of PHY it is.  And
maybe one day, someone who is familiar with the inner workings of this
PHY will fill in a more correct driver.
