I'm somewhat on the fence about these. Originally only devices with a 
bus or child nodes included a common schema. For 'simple' providers 
with mainly a '#<provider>-cells' property, we had to set the 
constraints on the number of cells anyways, so referencing another 
schema doesn't save anything. It is nice to declare the 'class' of the 
device though.

It makes the schema be applied twice (if the node name matches). That's 
not all bad because it finds cases of wrong node name. However, 
sometimes we have devices which are multiple providers and can't set the 
node name. So those can't reference interrupt-controller.yaml.

It also means that 'interrupt-map' for example is now valid. That could 
be fixed by splitting 'interrupt-map' related properties to its own 
schema.
