From: Rameshwar Prasad Sahu <rsahu@xxxxxxx>
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
