Subject: [PATCH v1 2/8] platform/x86: intel/pmc: Move variable declarations and definitions to header and core.c
From: Xi Pardee <xi.pardee@...el.com>
Move the msr_map variable declaration to core.h and move the pmc_lpm_modes
definition to core.c.
This is a prepartory patch for redesigning the pmc core driver as the
variables will be used in multiple PCH specific files.
