Subject: [PATCH v1 0/8] Redesign the pmc core driver

This patch series focuses on redesigning the PMC core driver for
maintainability and readability. Moving PCH specific structures and
functions to separate c files, simplifies core.c file and makes it
easier to add new platforms in future. The series includes two
preparatory patches that lays the ground work for the redesign. The
patch series also adds legacy support for Meteor Lake.

This redesign adds following c files to support different PCHs. There
are no functional changes involved for the already supported platforms.

spt.c: Sunrise Point PCH supports: Sky Lake, Sky Lake L, Kaby Lake,
Kaby Lake L
cnp.c: Cannon Lake Point PCH supports: Cannon Lake L, Comet Lake,
Comet Lake L
icl.c: Ice Lake PCH supports: Ice Lake L, Ice Lake NNPI, Jasper Lake
tgl.c: Tiger Lake PCH supports: Tiger Lake, Tiger Lake L, Alder Lake L,
Alder Lake N, Rocket Lake, Raptor Lake P, Elkhart Lake
adl.c: Alder Lake PCH supports: Alder Lake, Raptor Lake, Raptor Lake S
mtl.c: Meteor Lake PCH supports: Meteor Lake

Patch 1: platform/x86: intel/pmc: Replace all the reg_map with init
functions
Patch 2: platform/x86: intel/pmc: Move variable declarations and
definitions to header and core.c
Patch 3: platform/x86: intel/pmc: Relocate Sunrise Point PCH support
Patch 4: platform/x86: intel/pmc: Relocate Cannon Lake Point PCH
support
