[PATCH 7/8] dt-bindings: dma: qcom: bam-dma: Add missing required properties

[Stephan Gerhold]

num-channels and qcom,num-ees are required when there are no clocks
specified in the device tree, because we have no reliable way to read them
from the hardware registers if we cannot ensure the BAM hardware is up when
the device is being probed.

This has often been forgotten when adding new SoC device trees, so make
this clear by describing this requirement in the schema.
