Use a 1-byte DMA buffer for management UART receives.
It sounds silly, but this gives us completion callbacks, so we don't spend out entire time slice polling the receive buffer for new characters (which kills performance for tasks that are doing real work). Besides, libcli wants to process a character at a time, so uart_cli_read just waits on the completion callback.
