This sensor doesn't provide accurate case temperature. Let's
disable thermal thresholds for the object tempearture reading from this
sensor.
BUG=chrome-os-partner:9599
TEST=Build success. System works fine.

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.

We can clear the reset cause in system pre-init now because of a
previous change which preserves it across a sysjump.

Group temperature sensors into different types so we only have to set
temperature threshold for each type instead of each sensor.

- Add #ifdef CONFIG_TEMP_SENSOR before #include'ing temp_sensor.h
which actually requires temp_sensor_id to be defined.
Revert the forward declare used earlier since it is not the
correct solution in this case.
- Add #ifdef CONFIG_CHARGER before calling charger_init()
