Subject: [PATCH v2 3/3] platform/x86: asus_wmi: Set default fan boost mode to normal
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.
