Don't move these into if/then schemas. Then we are duplicating the
names, and there is no reason to keep them aligned for new compatibles.

Hi Rob,
As we have one extra reg property (dma) required for sa8775p-pcie-ep,
isn't it expected to be moved in if/then as per number of regs
required. Anyways we would have duplication of some properties for new
compatibles where the member numbers differs for a property.
Are you suggesting to add the extra reg property (dma) in the existing
reg and reg-names list, and add minItems/maxItems for all compatibles
present in this file ?

Here we have defined reg and interrupt per platform as clocks is defined.
