tools/power turbostat: Add support for Hygon Fam 18h (Dhyana) RAPL

Commit feb13c04627bf6a1973b ("tools/power turbostat: Add support for AMD
Fam 17h (Zen) RAPL") and the commit f03ec4d094bd3ee33a66 ("tools/power
turbostat: Also read package power on AMD F17h (Zen)") add AMD Fam 17h
RAPL support.

Hygon Family 18h(Dhyana) support RAPL in bit 14 of CPUID 0x80000007 EDX,
and has MSRs RAPL_PWR_UNIT/CORE_ENERGY_STAT/PKG_ENERGY_STAT. So add Hygon
Dhyana Family 18h support for RAPL.

Already tested on Hygon multi-node systems and it shows correct per-core
energy usage and the total package power.
