dt-bindings: PCI: host-bridges: Switch from deprecated pci-bus.yaml
dtschema package with core schemas deprecated pci-bus.yaml schema in
favor of pci-host-bridge.yaml.  Update all bindings to use the latter
one.

The difference between pci-bus.yaml and pci-host-bridge.yaml is only in
lack of "reg" property defined by the latter, which should not have any
effect here, because all these bindings define the "reg".

The change is therefore quite trivial, however it requires dtschema
package v2024.02 or newer.
