* Increase available bits, IN: 16 to 24, FAN: 8 to 12,
  TEMP: 6 to 12
* Reorder alarm/beep definitions to match in order to allow
  additional inputs in the future
* Remove comments about 'unused' bits as probe() is a better
  reference

Testing note:
* Tested on nct6799 with IN/FAN/TEMP, and changing min/max/high/hyst,
  that triggers the corresponding alarms correctly. Good confirmation
  on the original mapping of the registers and masks.
  As to be expected, only 4 fans and 2 temps (fixed) have limits
  currently on nct6799 on my board.
* Trouble with testing intrusion alarms and beeps, no way to confirm
  those. As I understand now, intrusion/caseopen is probably not
  connected on my board.
  And I haven't seen a buzzer on a board in ages.
