Christian Mauderer 779847a5ef bsp/atsam: Optionally use DMA for UART Rx ...

If the system is busy with other interrupts and the UART is set to a
fast baud rate, it's possible to loose UART interrupts and therefore
characters. This allows to optionally enable a DMA for the UARTs so that
a number of lost interrupts can be tolerated.

The number of DMAs on this chip is limited and not not all applications
need that feature. Therefore the DMA is disabled by default.
