This will be used in a follow-up CL to return specific error codes (not powered, not calibrated, etc.) BUG=chrome-os-partner:15174 BRANCH=link TEST=manual Power on system. 'temps' should return all good temps. Power off system (into S5) Only ECInternal temp should work; others should return Error 1 'gpioset enable_vs 1' and wait a second Now all the I2C temps should display good data, but PECI will still be error 1.
