dt-bindings: dma: qcom,bam-dma: Document BAM v2.0.0 compatible

Document compatible string for bam v2.0.0 version found on kaanapali.
BAM v2.0.0 differs from the earlier v1.7.X revision in terms of register
layout and offsets, requiring a distinct compatible for correct hardware
description.

Also add a new example for BAM v2.0.0 to illustrate a more complete
configuration than the existing v1.4 example. The new example covers
64-bit address and size cells, IOMMU bindings and execution
environment–related properties required on newer platforms.
