perf vendor events arm64: Fix incorrect Hisi hip08 L3 metrics
[ Upstream commit e9229d5b6254a75291536f582652c599957344d2 ]
Commit 0cc177cfc95d565e ("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.
