Subject: [PATCH v2 1/2] dt-bindings: PCI: qcom-ep: Add support for QCS9100
 SoC

Add devicetree bindings support for QCS9100 SoC. It has DMA register
space and dma interrupt to support HDMA.
QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p
platform use non-SCMI resource. In the future, the SA8775p platform will
move to use SCMI resources and it will have new sa8775p-related device
tree. Consequently, introduce "qcom,qcs9100-pcie-ep" to describe non-SCMI
based PCIe.
