fixes intermittent loss of connectivity on 1Gbit port, with log message:
> 803x_aneg_done: SGMII link is not ok
Thanks to David Bauer for pointing me in the right direction
I just had to figure out the right bus_id, which you find in this log:
> ag71xx ag71xx.1: connected to PHY at gpio-1:00 [uid=004dd074, driver=Atheros
> 8031 ethernet]
Fixes FS#2236
