Please drop the '0x' from the unit address in all instances.

No need to list 'status="okay"', it's the default. It might
make sense to change this to 'status="disabled"' though, if the ports
might be unused on some boards.

I don't understand this part: why do you add extra nodes here that only
contain a status property?

Note that if you add the devices to the per-soc file instead of the
per-board file, you can just access the nodes by label.
