Ok. Here it is. netdev and linux-serial Cc'ed.

- get rid of `model = "UCC"' in the ucc nodes
It isn't used anywhere, so remove it. If we'll ever need something
like this, we'll use compatible property instead.
- replace last occurrences of device-id with cell-index.
Drivers are modified for backward compatibility's sake.
