When hardware flow-control is disabled, manual toggling of the UART's reset line (RTS) using userland applications (e.g. stty) is not possible, since the ASC IP does not provide this functionality in the same was as some other IPs do. Thus, we have to do this manually. This set ensures the correct Pinctrl groups are configured and obtained for both manual toggling of the RTS line and for the IP to take over the lines when HW flow-control is requested by the user.
