dt-bindings: PCI: qcom,pcie-qcs404: Move QCS404 to dedicated schema

Move QCS404 PCIe devices from qcom,pcie.yaml binding to a dedicated file
to make reviewing and maintenance easier.

New schema is equivalent to the old one with few changes:
 - Adding a required compatible, which is actually redundant.
 - Drop the really obvious comments next to clock/reg/reset-names items.
