Currently MIPS allnoconfig with CONFIG_ATH25=y fails to link due to
missing support for early_serial_setup():
LD vmlinux
arch/mips/ath25/devices.o: In function ath25_serial_setup':
devices.c:(.init.text+0x68): undefined reference to 'early_serial_setup'
Rather than adding dependencies to the platform to force inclusion of
SERIAL_8250_CONSOLE together with it's dependencies like TTY, HAS_IOMEM,
etc, just make ath25_serial_setup() a no-op when the dependency is not
selected in the kernel config.
