Subject: [PATCH v2] 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.
