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.
