perf vendor events power9: Remove UTF-8 characters from JSON files
[ Upstream commit 5d9df8731c0941f3add30f96745a62586a0c9d52 ]
Commit 3c22ba5243040c13 ("perf vendor events powerpc: Update POWER9
events") added and updated power9 PMU JSON events. However some of the
JSON events which are part of other.json and pipeline.json files,
contains UTF-8 characters in their brief description. Having UTF-8
character could breaks the perf build on some distros.
Fix this issue by removing the UTF-8 characters from other.json and
pipeline.json files.
Result without the fix:
