Subject: [PATCH linux-next] thermal: int340x: processor_thermal: Ack all PCI interrupts

All interrupts from the processor thermal PCI device requires ACK. This
is done by writing 0x01 at offset 0xDC in the config space. This is
already done for the thereshold interrupt. Extend this for the workload
hint interrupt.
