link: Temp sensor read can return an error code
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.
