thermal: int340x: processor_thermal: Support shared interrupts

Browse Source 
commit 096597cfe4 upstream.

On some systems the processor thermal device interrupt is shared with
other PCI devices. In this case return IRQ_NONE from the interrupt
handler when the interrupt is not for the processor thermal device.
