perf vendor events riscv: Add StarFive Dubhe-80 JSON file

StarFive's Dubhe-80 supports raw event id 0x00 - 0x22.  The raw events
are enabled through PMU node of DT binding.  Besides raw event, add
standard RISC-V firmware events to support monitoring of firmware event.

Example of PMU DT node:

  pmu {
  	compatible = "riscv,pmu";
  	riscv,raw-event-to-mhpmcounters =
  		/* Event ID 1-31 */
  		<0x00 0x00 0xFFFFFFFF 0xFFFFFFE0 0x00007FF8>,
  		/* Event ID 32-33 */
  		<0x00 0x20 0xFFFFFFFF 0xFFFFFFFE 0x00007FF8>,
  		/* Event ID 34 */
  		<0x00 0x22 0xFFFFFFFF 0xFFFFFF22 0x00007FF8>;
  };

Example of 'perf stat' output:

  [root@user]# perf stat -a \
  	-e access_mmu_stlb \
  	-e miss_mmu_stlb \
  	-e access_mmu_pte_c \
  	-e rob_flush \
  	-e btb_prediction_miss \
  	-e itlb_miss \
  	-e sync_del_fetch_g \
  	-e icache_miss \
  	-e bpu_br_retire \
  	-e bpu_br_miss \
  	-e ret_ins_retire \
  	-e ret_ins_miss \
