Add a reference to snps,dw-pcie.yaml (and indirectly pci-bus.yaml) schemas.
With this, the common bus properties can be dropped from the schema.

This applies on top of Mauro's snps,dw-pcie.yaml series which I've 
applied to the DT tree.

While at it, I'll change to a non-bouncing address for LGM SoC[1]:
