platform/x86/intel: power-domains: Add interface to get Linux die ID 
The die ID in the Linux topology sysfs is a logical identifier that
differs from the one presented in CPUID leaf 0x1F or via MSR 0x54.

Introduce an interface that returns the Linux CPU die ID based on a
given package ID and power domain ID. This mapping is stored during the
CPU online callback in an array.

platform/x86/intel: TPMI domain id and CPU mapping 
Each TPMI power domain includes a group of CPUs. Several power
management settings in this case applicable to a group of CPUs.
There can be several power domains in a CPU package. So, provide
interfaces for:
- Get power domain id for a Linux CPU
- Get mask of Linux CPUs in a power domain

Hardware Punit uses different CPU numbering, which is not based on
APIC (Advanced Programmable Interrupt Controller) CPU numbering.
The Linux CPU numbering is based on APIC CPU numbering. Some PM features
like Intel Speed Select, the CPU core mask provided by the hardware is
based on the Punit CPU numbering. To use the core mask, this mask
needs to be converted to a Linux CPUs mask. So, provide interfaces for:
- Convert to a Linux CPU number from a Punit CPU number
- Convert to a Punit CPU number from a Linux CPU number

On each CPU online, MSR 0x54 is used to read the mapping and stores in
a per cpu array. Create a hash for faster searching of a Linux CPU number
from a Punit CPU number.
