Description: Support DMA transfers on AT91 serial port

More info: Say Y here if you wish to use the PDC to do DMA transfers to and from the Atmel AT91 serial port. In order to actually use DMA transfers, make sure that the use_dma_tx and use_dma_rx members in the atmel_uart_data struct is set appropriately for each port. Note that break and error handling currently doesn't work properly when DMA is enabled. Make sure that ports where this matters don't use DMA.
