[PATCH v2 8/8] perf/tools/pmu-events/powerpc: Add hv_24x7 socket/chip level metric events

[Kajol Jain]

The hv_24×7 feature in IBM® POWER9™ processor-based servers provide the
facility to continuously collect large numbers of hardware performance
metrics efficiently and accurately.
This patch adds hv_24x7  metric file for different Socket/chip
resources.

Result:

power9 platform:

command:# ./perf stat --metric-only -M Memory_RD_BW_Chip -C 0
           -I 1000 sleep 1

time MB       Memory_RD_BW_Chip_0 MB   Memory_RD_BW_Chip_1 MB
1.000192635                      0.4                      0.0
1.001695883                      0.0                      0.0
