Add option to adjust delay for indiviual temperature sensor
Perviously we have a 10-second delay for all temperature sensor. This is
not suitable for CPU temperature. Let's change that to have an option to
set the delay length for each temperature sensor. And also shorten the
delay of TMP006 sensor to 7 seconds, that of EC internal temperature to
4 seconds, and that of PECI CPU temperature to 0 second.

TEST=Check EC issued warning as soon as CPU temperature reached the
threshold.
