hwmon: (coretemp) Increase limit of maximum core ID from 32 to 128. 



A new limit selected arbitrarily as power of two greater than
required minimum for Xeon Phi processor (72 for Knights Landing).

Currently driver is not able to handle cores with core ID greater than 32.
Such attempt ends up with the following error in dmesg:
coretemp coretemp.0: Adding Core XXX failed
