[PATCH v2 1/1] dt-bindings: dma: Add support for SM6115 and QCS2290 SoCs

[Bhupesh Sharma]

Add new compatible for BAM DMA engine version v1.7.4 which is
found on Qualcomm SM6115 and QCS2290 SoCs. Since its very similar
to v1.7.0 used on SM8150 like SoCs, mark the comptible scheme
accordingly.

While at it, also update qcom,bam-dma bindings to add comments
which describe the BAM DMA versions used in SM8150 and SM8250 SoCs.
This provides an easy reference for identifying the actual BAM DMA
version available on Qualcomm SoCs.

Changes since v1:
 ~ v1 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230320071211.3005769-1-bhupesh.sharma@linaro.org/
 ~ Addressed Konrad's comments on v1, where he suggested how compatibles
   should be used for SoCs which support BAM DMA engine v1.7.4
 ~ Dropped v1's [PATCH 2/2] in v2.

All compatibles upstream are QCM2290-themed, let's keep it consistent.

The robotics SoC is QRB2210, but this should be QCM.

Sure, will be addressed in v2.

Thanks.
