mainline inclusion
from mainline-v5.12-rc3
commit 4e4cb8ca
category: cleanup
bugzilla: 175148
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4e4cb8ca48bd68c00df67c10ff867016abb7391f



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

The sanity check for counter index has been done in the function
hisi_uncore_pmu_get_event_idx, so remove the redundant interface
hisi_uncore_pmu_counter_valid() and sanity check.
