Add function which allows fetching the default FCR register setting from platform data for DM , while retaining old behavior for non-DM by returning UART_FCRVAL.

V2: If CONFIG_DM_SERIAL and DEBUG_UART are enabled, the ns16550_getfcr() can be invoked with NULL plat data . Check for this case and return the default UART_FCRVAL then. V3: It turns out that if DEBUG_UART is defined, $port points directly to hardware registers. Add additional ifdef to handle the case where debug uart is enabled with DM_SERIAL correctly. V4: Use UART_FCRVAL in _debug_uart_init() directly
