hwmon: peci: Add cputemp driver 



Add peci-cputemp driver for Digital Thermal Sensor (DTS) thermal
readings of the processor package and processor cores that are
accessible via the PECI interface.

The main use case for the driver (and PECI interface) is out-of-band
management, where we're able to obtain the DTS readings from an external
entity connected with PECI, e.g. BMC on server platforms.
