Anton Staaf 137959bb88 USART: Add flexibility needed to support DMA 
In order to support DMA transfers in one or both directions the usart
driver needs to be configurable with producer/consumer operations and
interrupt handler functions.  These are now packaged up in the usart_rx
and usart_tx structs, and versions for interrupt driven RX and TX are
provided.
