perf tools: Add support to specify pmu style event
Added new event rule to the event definition grammar:
event_def: event_pmu |
...
event_pmu: PE_NAME '/' event_config '/'
Using this rule, event could be now specified like:
cpu/config=1,config1=2,config2=3/u
where pmu name 'cpu' is looked up via following path:
${sysfs_mount}/bus/event_source/devices/${pmu}
and config options are bound to the pmu's format definiton:
${sysfs_mount}/bus/event_source/devices/${pmu}/format
The hardcoded config options still stays and have precedence
over any format field defined with same name.
