Yes, I think if we don't expect any future Synopsys/Designware branded
devices to use this, using ethernet/arc is fine.

The main reason to still use a different name is so we will be able
to group it with other drivers for designware ethernet controllers.

The only one I'm currently aware of is drivers/net/ethernet/stmicro/stmmac/.
If we wanted to ahve a designware directory, we should probably move that
as well.

I'll leave it up to you (or Dave, if he has a strong opinion).
