When none of temp sensors' temp/fan speed profile is not set(zero),
thermal control will set 0% duty over initial fan speed setting.
This patch allows fan under EC control at inital max speed
till host's DPTF sets proper fan speed.
BRANCH=master
BUG=none
TEST=1. check if fan is running at max speed until ChromeOS UI comes up.
2. check if fan is running when system is in recovery mode.
