power: smb135x-charger: Disable TEMP MONITOR in parallel charger mode 



The parallel SMB135x charger configuration may share battery thermistor
with PMIC and hence the default configuration has TEMP MONITOR enabled.
As the battery-temperature based parallel charger control is managed in SW,
disable the hardware TEMP MONITOR configuration on SMB135x.
