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:

I checked and this hasn't hit mainstream, is it already merged on a tree
where this is slated to be submitted in the next window? If so please
let me know which one so that I can merge it on perf/core.

I haven't picked it up. I guess the kernel changes are mainly in
powerpc, but I'd at least need an ack from eg. Peter for the generic
perf uapi change.

Done :-)
