Add binding describing the Qualcomm PCIe switch, QPS615,

To match spec usage:
s/Aspm/ASPM/
s/l0s/L0s/
s/l1/L1/

Other than the fact that qps615 needs the driver to configure these,
there's nothing qcom-specific here, so I suggest the names should omit
"qcom" and include "aspm".


In that case, these properties should be documented in dt-schema:
https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/pci/pci-bus-common.yaml

I am fine to move to pci-bus-common.yaml but currently these are being used by qps615 only I hope that is fine.
