Hi,

I've just been looking closer at this driver, and it seems that we can
drop the "legacy_pre_march2020" flag, and in doing so, delete the
ag71xx_mac_pcs_get_state and ag71xx_mac_an_restart functions entirely,
removing them from ag71xx_phylink_mac_ops.

Should this driver need to deal with the PCS - in other words, to
modify the advertisement, then it will need to make use of the
phylink_pcs support.

I'll send a v2 in a day or two.

Thanks!
