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%.
Changes in v2:
- rebase onto cryptodev tree
- split the patch 3/4 up to 3 independent patches
- remove the patch 4/4, the fix is not for cryptodev tree

Talitos: Support for async_tx XOR offload
fsl-dma: remove attribute DMA_INTERRUPT of dmaengine
fsl-dma: change the release process of dma descriptor
fsl-dma: use spin_lock_bh to instead of spin_lock_irqsave
