dmaengine: Add support for APM X-Gene SoC DMA engine driver
This patch implements the APM X-Gene SoC DMA engine driver. The APM X-Gene
SoC DMA engine consists of 4 DMA channels for performing DMA operations.
These DMA operations include memory copy, scatter-gather memory copy,
raid5 xor, and raid6 p+q offloading.
