perf/x86/rapl: Enable Apollo Lake RAPL support
This patch enables RAPL counters (energy consumption counters)
support for Intel Apollo Lake (Goldmont) processors (Model 92):
RAPL of Goldmont, unlikes ESU increment of Silvermont/Airmont,
it likes the Haswell microarchitecture in 1/2^ESU joules and
supports power domains in PP0/PP1/PKG/RAM.
ESU and power domains refer to Intel Software Developers' Manual,
Vol. 3C, Order No. 325384, Table 35-12.
Usage example:
$ perf list
$ perf stat -a -e power/energy-cores/,power/energy-pkg/ sleep 10
