If SERIAL_8250 is compiled as a module, the platform specific setup for Loongson will be a module too, and it will not work very well. At least on Loongson 3 it will trigger a build failure, since loongson_sysconf is not exported to modules. Fix by making the platform specific serial code always built-in.
