----------------------------------------------------------------------

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.

  							# -40.19 other_branch
  3,564,316,780	BR_MIS_PRED				# 0.51 indirect_branch
