The type should be PERF_TYPE_HARDWARE not PERF_TYPE_RAW. The real hybrid
PMU type can be found in the high 32 of attr.config.

/*
* attr.config layout for type PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE
* PERF_TYPE_HARDWARE: 0xEEEEEEEE000000AA
* AA: hardware event ID
* EEEEEEEE: PMU type ID

Something as below should work.
