This patch series adds support for AMD Fam17h RAPL counters. As per
AMD PPR, Fam17h support RAPL counters to monitor power usage. The RAPL
counter operates as with Intel RAPL. Therefore, it is beneficial to
re-use existing framework for Intel, especially to allow existing tools
to seamlessly run on AMD.

From the user's point view, this series enables the following two sysfs
entry on AMD Fam17h:
  /sys/class/powercap/intel-rapl/intel-rapl:0/energy_uj
  /sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:0/energy_uj
