Add JSON file of T-HEAD C9xx series events. The event idx (raw value) is summary as following: event id range | support cpu 0x01 - 0x2a | c906,c910,c920 The event ids are based on the public document of T-HEAD and cover the c900 series. These events are the max that c900 series support. Since T-HEAD let manufacturers decide whether events are usable, the final support of the perf events is determined by the pmu node of the soc dtb.
