    Commit 0cc177cf ("perf vendor events arm64: Add Hisi hip08 L3
    metrics") add L3 metrics of hip08, but some metrics (IF_BP_MISP_BR_RET,
    IF_BP_MISP_BR_RET, IF_BP_MISP_BR_BL) have incorrect event number due to
    the mistakes in document, which caused incorrect result. Fix the
    incorrect metrics.
    
    Before:
    
      65,811,214,308	armv8_pmuv3_0/event=0x1014/	# 18.87 push_branch
      							# -40.19 other_branch
      3,564,316,780	BR_MIS_PRED				# 0.51 indirect_branch
      							# 21.81 pop_branch
    
    After:
    
      6,537,146,245	BR_MIS_PRED			# 0.48 indirect_branch
      						# 0.47 pop_branch
      						# 0.00 push_branch
      						# 0.05 other_branch
    
    Fixes: 0cc177cf ("perf vendor events arm64: Add Hisi hip08 L3 metrics")
