Bill Richardson 6527d9e841 samus: Use motherboard temp sensors for fan control, too
This adds some temp limits from the motherboard die sensors to
use in determining the desired fan speed.

I'm also bumping the minimum PECI temp up a bit, since it varies
rapidly. At room temp the motherboard sensors will generally
request a little bit of cooling, but in cool environments it's
likely that the PECI changes will become the major annoying factor.

BUG=chrome-os-partner:34789
BRANCH=ToT,samus
TEST=manual

Watch/listen to fans. They shouldn't turn off and on as much.
