hwmon: (nct7904) Fix incorrect temperature limitation register setting of LTD.
According to kernel hwmon sysfs-interface documentation, temperature
critical max value, typically greater than corresponding temp_max values.
Thus, reads the LTD_HV_HL (LTD HIGH VALUE HIGH LIMITATION) and LTD_LV_HL
(LTD LOW VALUE HIGH LIMITATION) for case hwmon_temp_crit and
hwmon_temp_crit_hyst. Reads the LTD_HV_LL (HIGH VALUE LOW LIMITATION)
and LTD_LV_LL (LOW VALUE LOW LIMITATION) for case hwmon_temp_max
and hwmon_temp_max_hyst.
