Alec Berg 78992e730b lm4: Fix potential false over-temperature on entry to S0 ...

This fixes a rare problem in which the EC could shutdown due to
a false over-temperature when entering S0 on Haswell architectures.
The fix involves requiring two valid reads of the temperature
sensor (out of the last 4 readings) in order to report it.

BUG=chrome-os-partner:24204
BRANCH=none
TEST=See bug report for a patch that recreates the bug at a
significantly higher rate then it would occur on its own. Using
that patch, I implemented this fix, and made sure that there
were no false over-temperatures reported.
