The AMD dbm690t mainboard uses the it8712f SIO with the

default 48MHz clock input. The Asus a8n_e uses the it8712f
with a 24MHz clock input. The it8712f early init code was
setting a 24MHz input clock(to support the a8n_e).
Since 48Mhz is the default I added a function to set 24MHz
input clock to the a8n_e.
