Discovery: Add Forward and Loopback USART configurations
Add example uses of the multi USART driver with DMA transmission and interrupt
based reception. USART1 is setup as a loopback device, it just echo's any
characters received. USART4 is forwarded over USB.
Also fix the alternate function mappings for USART3 and USART4, and add
comments for each section of board.c.
