[PATCH 6.5 092/285] perf vendor events arm64: Remove L1D_CACHE_LMISS from AmpereOne list

6.5-stable review patch.  If anyone has any objections, please let me know.

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

From: Ilkka Koskinen <ilkka at os.amperecomputing.com>

[ Upstream commit b8af10062df3c23fe002c3f187389bb263b3eb20 ]

amperene/cache.json file tried to include L1D_CACHE_LMISS while it
doesn't exist in common-and-microarch.json. While this bug doesn't seem to
cause issue in newer kernels with jevents.py script, it prevents building
older perf tools with the backported patch.
