This DMA receiver uses a separate small circular buffer to DMA into.
This allows the DMA transaction to be made circular, and thus it does
not require the interrupt latency to be low enough to setup the next
transfer before the next character comes in.
Additional diagnostics output have been added to the usart_info console
command to facilitate tuning of the FIFO size.

The USART peripheral in the L and F families is different enough to need
different receive drivers. In particular, the L family USART perihperal
has no way of disabling the overflow error bit. So for that family we
check and clear the bit, and keep a count of overflows.
