ASoC: wsa-analog: update TEMP_OP disable before bandgap disable 



After enable temp sensor to register thermal zone, it is left On
and not disabled it when disable path. But bandgap is disabled at
disable path. So temp sensor is being left on without bandgap, there is
chance that it can be fed with wrong/unexpected value from ADC as per HW
team. Disable temp sensor in turn off sequence before bandgap disable
happen.
