Hi,

This is the version two of the patches with DMA support for
spi-at91-usart driver. 

Changes in v2:
- specified in bindings order of dmas and dma-names
- changed DMA_FROM_DEVICE to DMA_DEV_TO_MEM and DMA_TO_DEVICE to
DMA_MEM_TO_DEV when dmaengine_prep_slave_sg is called

Changes in v1:
- added DMA support
