Set default fan boost mode to normal for multiple reasons:

1) existing code assumes that laptop started in normal mode and that is
   not always correct.
2) FX705DY/FX505DY starts in silent mode and under heavy CPU load it
   overheats and drops CPU frequency to 399MHz [1]. Setting fan mode to
   normal avoids overheating.

This can be refactored

if (!foo)
  return 0;
...
return bar(asus);
