Subject: [PATCHv2 10/12] staging: ti-soc-thermal: fix condition to apply hyst

While updating talert thresholds, threshold cold must
always be lower than threshold hot. This patch fixes
the function ti_bandgap_update_alert_threshold to only
change the thresholds by applying a hysteresis when
they violate this condition.
