For the records, this should rather be marked as a sync from the Linux
tree, where this was conveniently merged just recently.

In the long run we should see if we can avoid those ethernet aliases,
since their only purpose seems to be to trigger U-Boot's MAC
generation, and I wonder if there is a simpler way. Using U-Boot's DM
interface to enumerate Ethernet devices comes to mind, for instance.
This would avoid the churn of funnelling those trivial DT changes
through Linux first.

I will apply this and push it for the merge window, after adding the
Linux tag.

Thanks!
Andre
