fdtdec: Support retrieving the name of a carveout
When retrieving a given carveout for a device, allow callers to query
the name. This helps differentiating between carveouts when there are
more than one.
This is also useful when copying carveouts to help assign a meaningful
name that cannot always be guessed.
