Migrate from genphy_config_eee_advert() to genphy_c45_write_eee_adv().

It should work as before except write operation to the EEE adv registers
will be done only if some EEE abilities was detected.

If some driver will have a regression, related driver should provide own
.get_features callback. See micrel.c:ksz9477_get_features() as example.

This patch causes network interface failures with all my xtensa qemu
emulations. Reverting it fixes the problem. Bisect log is attached
for reference.

Also affected are arm:cubieboard emulations, with same symptom.
arm:bletchley-bmc emulations crash. In both cases, reverting this patch
fixes the problem.
