perf mem/c2c: Fix perf_mem_events to support powerpc
PowerPC hardware does not have a builtin latency filter (--ldlat) for
the "mem-load" event and perf_mem_events by default includes
"/ldlat=30/" which is causing a failure on PowerPC. Refactor the code to
support "perf mem/c2c" on PowerPC.
This patch depends on kernel side changes done my Madhavan:
