powerpc/perf: Add stalled-cycles events
Support for stalled-cycles-frontend and stalled-cycles-backend is
added for e500-based processors.
The following mappings are used:
stalled-cycles-frontend or idle-cycles-frontend:
Com:18 Cycles decode stalled
stalled-cycles-backend or idle-cycles-backend
Com:19 cycles issue stalled
