Patchset adds new macros for mem_hops field which can be
used to represent remote-node, socket and board level details.
Currently the code had macro for HOPS_0, which corresponds
to data coming from another core but same node.
Add new macros for HOPS_1 to HOPS_3 to represent
remote-node, socket and board level data.
For ex: Encodings for mem_hops fields with L2 cache:
L2 - local L2
L2 | REMOTE | HOPS_0 - remote core, same node L2
L2 | REMOTE | HOPS_1 - remote node, same socket L2
L2 | REMOTE | HOPS_2 - remote socket, same board L2
L2 | REMOTE | HOPS_3 - remote board L2
Patch 1 & 2 adds tool and kernel side changes to add new macros for
mem_hops field
Patch 3 add data source encodings for power10 and older platforms
to represent data based on newer composite PERF_MEM_LVLNUM* fields
Patch 4 add data source encodings with proper sub_index used to
represent memory/cache level data for power10 platform.
