Summary of changes:

Till the commit:
"tools/power/x86/intel-speed-select: Get punit core mapping
information"

All patches just lays foundation for adding new hardware interface
in addition to existing MSR/MMIO interface.

All patches prefixed with "Abstract" just adds individual hardware
callback for functions called from the core processing.

The mailbox processing is abstracted to a new file with callbacks.

In addition some changes to reduce duplicated code for display
of TRL level.

Patch "Introduce Punit ID concept and add related API" add further
abstraction in addition to existing package and die scope.

-----------
tools/power/x86/intel-speed-select: Get punit core mapping information
-Adds a new way to get package/die/punit information for each CPU.
-----------

Introduce TPMI interface support
- Implement all abstracted callbacks above to use TPMI IOCTL interface.
-----------

tools/power/x86/intel-speed-select: Display punit info
- With TPMI the granularity is per punit, which can be multiple in a
package/die.
----------

tools/power/x86/intel-speed-select: Remove cpu mask display for non-cpu
power domain
tools/power/x86/intel-speed-select: Display fact info for non-cpu power
domain
-There are some power domains with no CPUs, the above patches adds CPU
as invalid for these domains
----------

tools/power/x86/intel-speed-select: Use cgroup v2 isolation
- Adds new option to use Cgroup CPU isolation instead of offline of CPUs
----------

tools/power/x86/intel-speed-select: Change TRL display for Emerald Rapids
- Emerald Rapid has multiple TRL levels and moves away from TRL level
based on instruction type
