[PATCH 2/6] dt-bindings: dma: qcom,bam: Document dma-coherent property

[Kaushal Kumar <quic_kaushalk@xxxxxxxxxxx>]

SDX75 BAM DMA controller has DMA-coherent support so define
it in the properties section, without which 'dtbs_check'
reports the following error:

  controller@1c9c000: 'dma-coherent' does not match any of the
  regexes: 'pinctrl-[0-9]+'
