helios: Modify EC fan control table
Modify EC fan control table by Thermal request. (#21)
BUG=b:136565336
BRANCH=none
TEST=Manual
Verify fan behavior by thermal team.
Remove DPTF and check fan speed with temperature.
When temperature over 65 degree, the fan start working.
When temperature over 85 degree, the fan full run.
And check system shutdown when temperature over 90 degree.
