For TI power management chip TPS40422, READ_TEMPERATURE_2 command is supported on page 1 of the chip, but the original driver(pmbus.c) only tried to detect this command on page 0, this will lead to a result that the temperature sensor in page 1 couldn't be detected. This change is to isolate the tps40422 driver from pmbus.c into a solo front-end driver.
