hwmon: Add driver for Texas Instruments TMP421/422/423 sensor chips

Add support for Texas Instruments TMP421/422/423 temperature sensor IC.

TI's TMP421/422/423 are I2C temperature sensor chips. These chips are
similar to TI's TMP401/411 chips, but with reduced functionality (only
temperature measurement). The chips have one local sensor and up to
three (TMP423) remote sensors.
