The same PMU driver has different PMU identifiers due to different hardware versions and types, but they may have some common PMU event. Since a Compat value can only match one identifier, when adding the same event alias to PMUs with different identifiers, each identifier needs to be defined once, which is not streamlined enough. So let "Compat" supports matching multiple identifiers for uncore PMU alias. For example, the Compat value {43401;436*} can match the PMU identifier "43401", that is, CMN600_r0p0, and the PMU identifier with the prefix "436", that is, all CMN650, where "*" is a wildcard. Tokens in Unit field are delimited by ';' with no spaces.

But "eventid=3Dxxx, type=3Dxxx" cannot be supported at present. If EventCode and ConfigCode is not added in the alias JSON file, the event description will add "event=3D0" by default. So, even if the event field is added to supplement "eventid=3Dxxx" and "type=3Dxxx", the final parsing result will be "event=3D0, eventid=3Dxxx, type=3Dxxx". Therefore, when EventCode and ConfigCode are missing in JSON, "event=3D0" is no longer added by default. EventIdCode and Type are added to the event field, and ConfigCode is moved into the event_field array which can also guarantee its original function.
