Subject: [PATCH] x86, perf: Fix __initconst declaration in rapl perf driver

From: Andi Kleen <ak@...ux.intel.com>

Fix a definition in the perf rapl driver. __initconst must
be applied to a const object, but to declare a const pointer
you need to use * const ..., not const ... *

This fixes a section attribute conflict with LTO builds.
