[LinuxBIOS] patch for EPIA vt8231_early_serial.c

[Ben Hewson]

The code was enabling interrupts for the serial port, possibly causing 
random hangs on boot.
I have replaced the 8250 initialisation code with that in uart8250.c

This seems to work ok for me, but I can't say for sure if it has stopped 
the random boot hangs,
as they were/are a bit random.
