[PATCH v2] dt-bindings: soc: airoha: Add the pbus-csr node for EN7581 SoC

[Lorenzo Bianconi]

Introduce pbus-csr document bindings in syscon.yaml for 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.
