Subject: [PATCH 0/3] Raid: enable talitos xor offload for improving performance

The following 4 patches enabling fsl-dma and talitos offload raid
operations for improving raid performance and balancing CPU load.

Write performance will be improved by 40% tested by iozone. CPU load
will be reduced by 8%.

Talitos: move the data structure into header file
Talitos: Support for async_tx XOR offload
fsl-dma: support attribute of DMA_MEMORY when async_tx enabled
Talitos: fix the issue of dma memory leak
