* 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
Tried different ways to define the bits (arrays by type - too long,
double dimensional - too complicated, a padding macro - rough to
read and checkpatch won't allow it), so kept the original
method as seems the neatest for readability, but expanded it to a
consistent 12 entries per row (8 too long, 16 too wide).
That way it's the least number of lines and easy to read.
All BITS now take up around 616 bytes instead of 352 bytes.
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.
