perf jevents: Support EventidCode and NodeType

The previous code assumes an event has either an "event=" or "config"
field at the beginning. For CMN neither of these may be present, as an
event is typically "type=xx,eventid=xxx".

So add EventidCode and NodeType to support CMN event description.

I compared pmu_event.c before and after compiling with JEVENT_ARCH=all,
they are consistent.
