dt-bindings: reserved-memory: Add restricted-dma-pool constraints

Browse Source 
The "restricted-dma-pool" definition prohibits combination with either
of the "no-map" and "reusable" properties, but this is only stated in
the description text. Add those constraints to the schema so we can
properly validate them.
