hwmon: (peci/cputemp) Fix crit_hyst returning delta instead of absolute temperature
The hwmon sysfs ABI expects tempN_crit_hyst to report the temperature at
which the critical condition clears, not the hysteresis delta from the
critical limit.
The peci cputemp driver currently returns tjmax - tcontrol for
crit_hyst_type, which is the hysteresis margin rather than the
corresponding absolute temperature.
Return tcontrol directly, and update the documentation accordingly.
