bsp/atsam: Optionally use DMA for UART RxHEADmaster
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. Close #4578
