After 57a38effa598 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091)
the macb1 interface refuses to work properly because it tries
to cling to address 0 which isn't able to communicate in broadcast with
the mac anymore. The micrel phy on the board is actually configured
to show up at address 1.
Adding the phy node and its real address fixes the issue.

Arnd, Olof, Kevin,

It seems late but, is it possible to queue this patch as a 4.0 fixes?

Without it, the 10/100 Ethernet on sama5d3 doesn't work if it's not used
by u-boot previously.

Bye,
