perf vendor events arm64: Remove L1D_CACHE_LMISS from AmpereOne list
[ 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.
