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

commit cc904f9cf26dc455cffbdf6e7eb86717e047d8ff upstream.

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
