powercap: Add AMD Fam17h RAPL support
Enable AMD Fam17h RAPL support for the power capping framework.
The support is as per AMD Fam17h Model31h (Zen2) and model 00-ffh
(Zen1) PPR.
Tested by comparing the results of following two sysfs entries and the
values directly read from corresponding MSRs via /dev/cpu/[x]/msr:
/sys/class/powercap/intel-rapl/intel-rapl:0/energy_uj
/sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:0/energy_uj
