Prepare for 8250 split; move fixed type initialization into serial8250_set_defaults(). This enables uart_config[] array to remain file scope in base port operations after the split. NB: the call to serial8250_init_fixed_type_port() from serial8250_register_ports() was added by commit b5d228cc4f85 ("serial: copy UART properties of UPF_FIXED_TYPE ports provisioned using early_serial_setup") specifically to support ports initialized by early_serial_setup(). Since serial8250_set_defaults() is called from early_serial_setup(), fixed type initialization is now already handled there before serial8250_register_ports() is called.
