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.
