The fans on samus have a recommended minimum duty cycle of 20% while running, but 30% in order to start. We've been using the EC's built-in fan controller for the start requirement, but it has a minimum fast-start duty cycle of 50%. It turns out that that speed is noticeably noisy. This change handles the startup with logic in the EC instead, so that the fan only tries to spin at 30% initially (or if it drops too much below the minimum turning speed). BUG=chrome-os-partner:33429 BRANCH=ToT,samus TEST=make buildall -j Boot the system, let it idle with the browser windows closed, the browse a bit, then idle. Listen for changes to the fans. Before, I could hear the fans kick in and out as the AP load changed. Now it's much quieter.
