This forces the fan PWM duty cycle to a fixed percentage (0-100). It's only
used for airflow testing.
BUG=chrome-os-partner:10747
TEST=manual
Using this ectool, try
ectool fanduty 0
ectool pwmgetfanrpm
ectool fanduty 50
ectool pwmgetfanrpm
ectool fanduty 100
ectool pwmgetfanrpm
You should see (and hear) the fan speed up. If you have an EC console, you
can run
faninfo
and it should show that the 'Target:' is unrelated to the 'Actual:' value.
