BCM5301X has 3 Ethernet controllers: GMAC0, 1, 2 which map to ports 5, 7
and 8 respectively of the internal switch. Future changes will turn on
management mode in the Ethernet switch driver (b53) which will require
us to use port 8.

I'm not exactly sure how Linux switch driver works, but from DT
perspective I think we should rather have *hardware* described instead
of a common Linux case.
If I'm right, we should rather have all 3 switch ports described (5, 7,
8) and have Linux just use the one it needs.
