The patch set add driver and device-tree bindings for a dma controller
on hisilicon ascend310/910 platform.

Changes v2 to v3:
	- 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()
