Add the remaining gpci requests that contain counters suitable for use
by perf. Omit those that don't contain any counters (but note their
ommision).

Changelog[v6]

[Jiri Olsa, Sukadev Bhattiprolu] Replace 'starting_index' with what
it really means for the event. Eg if starting_index refers to a
partition_id for an event, allow user to specify a value for
partition_id rather than 'starting_index'. Also use a =? to indicate
required parameters: eg partition_id=?
