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.

s/dma/DMA/ above for consistency.

Add blank line here if this is a paragraph break.

s/drived/derived/

This patch doesn't add anything related to SCMI, so this paragraph
seems like a distraction.

The first paragraph seems a bit of a distraction too, since the patch
doesn't say anything about DMA register space or interrupt.

A blank line will be added in the next verion of the patch series.

This patch is used to support QSC9100. QCS9100 uses non-SCMI resources, 
so there is nothing related to SCMI in this patch.

Only SA8775p will move to use SCMI resources in the future.

I will update this commit message as follows in the next version of the 
patch series.

"Add devicetree bindings support for QCS9100 PCIe EP compatible."

The paragraph can be removed from the commit message in next patchsets.
Let me know if others looks good to you or not.

agree. Suggest to remove the first paragraph as well.

After considering the feedback provided on the subject, We have decided
to keep current SA8775p compatible and ABI compatibility in drivers.
Let's close this session and ignore all the current patches here.
Thank you for your input.
