Subject: MIPS: Loongson: Make platform serial setup always built-in.
From: Aaro Koskinen <aaro.koskinen@xxxxxx>
commit 26927f76499849e095714452b8a4e09350f6a3b9 upstream.
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.
