hwmon: (nct6775) Additional TEMP registers for nct6799 

Additional TEMP registers for nct6798d, nct6799d-r and nct6796d-s
This allows the max/max_hyst/crit attributes to be shown/stored

* Increase NUM_TEMP from 10 to 12
* Separate TEMP/MON_TEMP/OVER/HYST/CRIT registers
* Rename "PECI Calibration" to include "TSI" too
* Update ALARM/BEEP bits for temps for 6799
* For 6799, keep temp_fixed_num at 6, but increase
  num_temp_alarms/num_temp_beeps to 7/8

Tested with NCT6799D-R showing additional sysfs attributes:
* temp3-temp8: max/max_hyst/beep/alarm
* temp3-temp6: crit/offset
