Nicolas Ferre 1ccc404a7f spi/spi-atmel: add dmaengine support 
Add dmaengine support.

Using "has_dma_support" member of struct is used to select
the transfer mode: dmaengine or pdc.

For the dmaengine transfer mode, it supports both 8 bits and 16 bits transfer.

For the dmaengine transfer mode, if it fails to config dmaengine,
or if the message length is less than 16 bytes, it will use the PIO transfer mode.
