thermal: int340x: processor_thermal: Use non MSI interrupts by default

There are issues in using MSI interrupts for processor thermal device.
The support is not consistent across generations. But the legacy PCI
interrupts work on all current generations.

Hence always use legacy PCI interrupts by default, instead of MSI.
Add a module param to use of MSI, so that MSI can be still used.
