Subject: [PATCH v9 1/2] dt-bindings: dma: Add support for SM6115 and QCM2290 SoCs

Add new compatible for BAM DMA engine version v1.7.4 which is
found on Qualcomm SM6115 and QCM2290 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.
