Subject: [PATCH 39/55] docs: perf: Fix PMU instance name of hisi-pcie-pmu

mainline inclusion
from mainline-v6.2-rc1
commit eb79f12b4c41dd2403a0d16772ee72fcd6416015
bugzilla: https://gitee.com/openeuler/kernel/issues/I8AU2M

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=eb79f12b4c41dd2403a0d16772ee72fcd6416015

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

The PMU instance will be called hisi_pcie<sicl>_core<core> rather than
hisi_pcie<sicl>_<core>. Fix this in the documentation.
