dt-bindings: dma: qcom,bam: require one of control methods

The BAM DMA resources can be controlled remotely (e.g. by trusted
environment; needs qcom,powered-remotely or qcom,controlled-remotely
properties) or locally. In the latter case we need to provide its
clock.

Require one of methods of such control to properly validate DTS.

dt-bindings: dma: Increase iommu maxItems for BAM DMA

Since SM8250 BAM DMA engine supports six iommu entries,
increase the maxItems in the iommu property section, without
which 'dtbs_check' would throw errors.

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.

dt-bindings: dma: drop unneeded quotes

Cleanup by removing unneeded quotes from refs and redundant blank lines.
No functional impact except adjusting to preferred coding style.

dt-bindings: dma: Make minor fixes to qcom,bam-dma binding doc

As a user recently noted, the qcom,bam-dma binding document
describes the msm8974 BAM DMA node in the 'example section'
incorrectly. Fix the same by making it consistent with the node
present inside 'qcom-msm8974' dts file, namely the 'reg' and
'interrupt' values which are incorrect in the 'example section'.

While at it also make two additioanal minor cleanups:
- mention Bjorn's new email ID in the document, and
- add SDM845 in the comment line for the SoCs on which
qcom,bam-v1.7.0 version is supported.
