This patch implements support for APM X-Gene SoC CRC32C h/w accelerator driver
and adds CRC32C computations support in dmaengine framework. APM X-Gene SoC has
DMA engine capable of performing CRC32C computations.

v2 changes:
	1. Added helper function in dmaengine framework
	2. Documented CRC32C support in Documentations/dmaengine/provider.txt
	3. Fixed algo name
	4. Fixed coding style issues
