drivers: thermal: bcl_pmic5: Incorporate thermometer encoding 



The BCL hardware doesn't notify the HLOS on thermometer encoded format.
This can lead to a situation where a higher vbat or ibat violation gets
triggered, but the lower violation doesn't.

Update the interrupt handling to handle this case. The irq handler will
notify the lower violation routine to mimic the thermometer encoding.
