Ian Rogers 9957d8c801 perf jevents: Add common software event json 
Add json for software events so that in perf list the events can have
a description.  Common json exists for the tool PMU but it has no
sysfs equivalent. Modify the map_for_pmu code to return the common map
(rather than an architecture specific one) when a PMU with a common
name is being looked for, this allows the events to be found.
