serial: mvf: enable FIFO even when using serial console
Enable FIFO unconditionally, even when CONFIG_SERIAL_CORE_CONSOLE
is turned on. Serial consoles get enabled anyway, but this compile
time switch lead to disabling FIFO for all serial ports. Not using
FIFO when using a serial port might lead to missing characters
quite easily.
