This patch adds automatic fan control for the CPU fan on the m57sli

board.

This is done via the ec_init routine in a source file in the
mainboard/gigabyte/m57sli directory. A Config variable 'HAVE_FANCTL' has been
added to notify superio.c to get the ec_init externally.

I (Ward) have tested this on the PLCC and the SOIC/SPI version of this board.
It works.
