FROMLIST: dt-bindings: PCI: qcom: Document the Glymur PCIe Controller

On the Qualcomm Glymur platform the PCIe host is compatible with the DWC
controller present on the X1E80100 platform. So document the PCIe
controllers found on Glymur and use the X1E80100 compatible string as a
fallback in the schema.
