hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-only

Browse source 
All chips in this chip series only support a single hysteresis value. Having
multiple writable hysteresis attributes is therefore confusing, since a single
write affects all hysteresis temperatures. Make all but one (temp1_crit_hyst)
read-only.

@ -51,6 +51,9 @@ This implementation detail implies the following:
was 80 degrees C, and the hysteresis was 75 degrees C, and you change
the critical limit to 90 degrees C, then the hysteresis will
automatically change to 85 degrees C.
* While hysteresis limits can be set for all critical limits, setting a single
hysteresis value affects the hysteresis values for all limits on all sensors.
* The hysteresis values can't be set independently. We decided to make
only temp1_crit_hyst writable, while all other hysteresis attributes
are read-only. Setting temp1_crit_hyst writes the difference between
temp1_crit_hyst and temp1_crit into the chip, and the same relative
hysteresis applies automatically to all other limits.
* The limits should be set before the hysteresis.
