Kajol Jain 26da4abfb3 powerpc/perf: Fix data source encodings for L2.1 and L3.1 accesses 
Fix the data source encodings to represent L2.1/L3.1(another core's
L2/L3 on the same node) accesses properly for power10 and older
plaforms.

Add new macros(LEVEL/REM) which can be used to add mem_lvl_num and remote
field data inside perf_mem_data_src structure.

Result in power9 system with patch changes:
