[PATCH v3 0/4] powercap: Enable RAPL for AMD Fam17h and Fam19h

[Victor Ding]

This patch series adds support for AMD Fam17h RAPL counters. As per
AMD PPR, Fam17h and Fam19h 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 or Fam19h:
  /sys/class/powercap/intel-rapl/intel-rapl:0/energy_uj
  /sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:0/energy_uj
