ec/chromeec: Enable auto fan control on startup

Several older ChromeOS boards have issues with fan control on cold boot
and/or on S3 resume, so add functionality to allow those boards to
programmatically enable auto fan control.

TEST=build/boot google/link, verify fan ramps up/down accordingly with
CPU load.
