thermal: intel: int340x: Support MSI interrupt for Lunar Lake

Browse source

The legacy PCI interrupt is no longer supported for processor thermal
device on Lunar Lake. The support is via MSI.

Add feature PROC_THERMAL_FEATURE_MSI_SUPPORT to support MSI feature per
generation. Define this feature for Lunar Lake processors.

There are 4 MSI sources:
 0 - Package thermal
 1 - DDR Thermal
 2 - Power floor interrupt
 3 - Workload type hint

On interrupt, check the source and call the corresponding handler.

Here don't need to call proc_thermal_check_wt_intr() and
proc_thermal_check_power_floor_intr() to check if the interrupt is for
those sources as there is a dedicated MSI interrupt.
