Revert "drivers/tty/serial: make 8250/8250_ingenic.c explicitly non-modular"
This reverts commit cafe1ac64023 ("drivers/tty: make serial 8250_ingenic.c explicitly non-modular"), which attempted to remove dead code but did not have the desired effect when the main 8250 driver was a loadable module itself. This would normally result in a link error, but as the entire drivers/tty/serial/8250/ directory is only entered when CONFIG_SERIAL_8250 is set, we never notice that the driver does not get built in this configuration.
