thermal: int340x: processor_thermal: Common function to clear SOC interrupt

Browse source

The SOC interrupt status register contains multiple interrupt sources
(workload hint interrupt and power floor interrupt). It is not possible
to clear individual interrupt source with read-modify-write, as it may
clear the new interrupt from the firmware after a read operation. It is
also not possible to set the interrupt status bit to 1 for the other
interrupt source, which is not part of clearing.

Hence, create a common function, to clear all status bits at once.

Call this function after processing all interrupt sources.
