[DT-SCHEMA PATCH V1] schemas: pci: Extend the meaning of 'linux,pci-probe-only'

[Vidya Sagar <vidyas@nvidia.com>]

Extend the meaning of 'linux,pci-probe-only' to cover the cases where
it is applicable only to a specific PCIe host bridge if defined in a
PCIe node instead of chosen node. Add the documentation for the same
in schemas/pci/pci-host-bridge.yaml
