[PATCH v5 2/2] platform/x86 asus_wmi: Set throttle thermal policy to default

From: Leonid Maksymchuk
Date: Sun Nov 24 2019 - 09:09:05 EST


ASUS TUF FX705DY/FX505DY starts in silent mode and under heavy
CPU load it overheats and drops CPU frequency to 399MHz and stays
at it until reboot [1]. Set throttle thermal policy to default
to avoid overheating and throttlig.
