perf vendor events power9: Add hv_24x7 socket/chip level metric events

Browse Source 
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
