thermal: intel: Add resources to handle directed package-level thermal interrupts

Browse source

When supported by hardware, a CPU requests to receive directed package-
level thermal interrupts by setting a designated bit in
IA32_THERM_INTERRUPT. It is sufficient to have one CPU per package handling
the interrupt.

Add an array to keep track of those CPUs as well as init and cleanup
functions. A subsequent changeset will designate a CPU per package to
handle the interrupt.
