brya: Set fan PWM frequency to 25 KHz
The brya fan spec calls for the PWM frequency to be 25 KHz. Many brya
variants already use 25 KHz as this is a common PWM frequency for fans.
BRANCH=none
BUG=none
TEST=changed fan speed with "fanduty" and confirmed resulting speed with
"faninfo" and physically.
