[PATCH 2/3] perf/x86/intel: Add Cannon Lake support of RAPL profiling

[Harry Pan]

This patch enables RAPL counters (energy consumption counters)
support for Cannon Lake processors.

ESU and power domains refer to Intel Software Developers' Manual,
Vol. 4, Order No. 335592.

Usage example:

$ perf list
$ perf stat -a -e power/energy-cores/,power/energy-pkg/ sleep 10
