From: Tom O'Rourke <Tom.O'Rourke at intel.com>

This patch makes SLPC enabled by default on
platforms with hardware/firmware support.

DO NOT MERGE: This patch is added for convenience in
reviewing SLPC patch series.  This patch should be
merged after validation results show benefits of using SLPC.
