bnxt_en: Expose threshold temperatures through hwmon

Browse source

HWRM_TEMP_MONITOR_QUERY response now indicates various
threshold temperatures. Expose these threshold temperatures
through the hwmon sysfs using this mapping:

hwmon_temp_max : bp->warn_thresh_temp
hwmon_temp_crit : bp->crit_thresh_temp
hwmon_temp_emergency : bp->fatal_thresh_temp

hwmon_temp_max_alarm : temp >= bp->warn_thresh_temp
hwmon_temp_crit_alarm : temp >= bp->crit_thresh_temp
hwmon_temp_emergency_alarm : temp >= bp->fatal_thresh_temp
