I don't follow what is the relationship between this and your other
series.

Only some partitions are nvmem nodes, so we shouldn't always include it.
Then we can't exclude nvmem properties from partition nodes which
aren't. We should identify those nodes by compatible and their schema
should reference partition.yaml and nvmem.yaml.

There's a general problem with the partition related schemas that
undefined properties are not caught. This is partly because
partition nodes can be nested and expressing that with the schema is
hard.
