There is only one register internally, where the hysteresis is stored
as a relative (or delta) value. So the difference between
temp2_crit_hyst and temp2_crit is always the same as the difference
between temp1_crit_hyst and temp1_crit. Same for temp3_crit_hyst.
That's why only one hyst file is writable.

The driver doesn't yet support the extended temperature format. This
could be added, you can either contribute it as a patch or wait for (or
even sponsor) someone to implement it for you.
