The nlm_early_serial_setup code needs the early_serial_setup symbol
which is only available if CONFIG_SERIAL_8250 is selected.
Fixes the following build problem:

arch/mips/built-in.o: In function `nlm_early_serial_setup':
setup.c:(.init.text+0x274): undefined reference to `early_serial_setup'
make: *** [vmlinux] Error 1
