The partition bindings fail to restrict undefined properties. This is 
primarily on fixed-partitions which can be nested and partition nodes 
without a compatible string. This series fixes those issues and then 
several problems exposed by restricting undefined properties. As part of 
this, the schema structure is reworked to follow more conventional 
structure of applying schemas by compatible and a schema only checks 1 
level of nodes (unless possible child nodes are fixed).

In theory, we could have all sorts of combinations of different 
partition types nesting, and those may or may not work. No attempt is 
made to support them here. Only the known cases are supported.

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
