dt-bindings: PCI: mediatek-gen3: Add mediatek,pbus-csr phandle array property
Introduce the mediatek,pbus-csr property for the pbus-csr syscon node
available on EN7581 SoC.
The Airoha pbus-csr block provides a configuration interface for the
PBUS controller used to detect if a given address is accessible on PCIe
controller.
