[PATCH v2 1/2] dt-bindings: dmaengine: zynqmp_dma: Add a new compatible string

[Abin Joseph]

Add compatible string "amd,versal2-dma-1.0" to support AMD Versal Gen 2
platform.

AMD Versal Gen 2 has 8 LPD DMA IPs in PS that can be used as general
purpose DMAs which is designed to support memory to memory and memory to
IO buffer transfer. Versal Gen 2 DMA IP has different interrupt register
offset.

Changes in v2:
- Rearrange the order of compatible.
- Remove example binding documentation.
