Subject: [PATCH 0/8] Add multiple PMCs support in pmc core driver

Newer platforms starting from Meteor Lake can have multiple PMCs.
This patch series include changes to enable pmc core driver to support
multiple PMCs for newer platforms. It adds devid and register maps to
enable IOE-P and IOE-M available on Meteor Lake platform. It also fixes
the register maps for SOC-M.

Patch includes:
platform/x86:intel/pmc: Update maps for Meteor Lake P/M platforms
platform/x86:intel/pmc: Combine core_init() and core_configure()
platform/x86:intel/pmc: Add support to handle multiple PMCs
platform/x86:intel/pmc: Enable debugfs multiple PMC support
platform/x86:intel/pmc: Discover PMC devices
platform/x86:intel/pmc: Use SSRAM to discover pwrm base address of primary PMC
platform/x86:intel/pmc: Add Meteor Lake IOE-P PMC related maps
platform/x86:intel/pmc: Add Meteor Lake IOE-M PMC related maps
