The patch set add driver and device-tree bindings for a dma controller

- Fix dts-binding error:
* Use "hisilicon" as a unified vendor prefix.
Changes v1 to v2:
- Fix dts-binding error:
* change "compatible" to two exact models: ascend310/ascend910.
* add vendor prefix for customized channel-map property.
* add $ref for customized channel-map property.
* remove unnecessary label in example.
- Logic change in probe function:
* If iommu sva feature is disabled, probe will not lead to failure
- Use common driver apis: dev_xxx() devm_xxx()
