From: Tom O'Rourke <Tom.O'rou...@intel.com>
Adds has_slpc to broxton info and adds broxton firmware version check
to sanitize_slpc_option.
v1: Adjusted slpc version check for major version 8.
Added message if version mismatch happens for easier debug. (Sagar)
v2-v3: Rebase.
v4: Commit message update.
