perf/x86/amd: Remove l1-dcache-stores event for AMD This is a long standing bug with the l1-dcache-stores generic event on AMD machines. My perf_event testsuite has been complaining about this for years and I'm finally getting around to trying to get it fixed. The data_cache_refills:system event does not make sense for l1-dcache-stores. Maybe this was a typo and it was meant to be for l1-dcache-store-misses? In any case, the values returned are nowhere near correct for l1-dcache-stores and in fact the umask values for the event have completely changed with fam15h so it makes even less sense than ever. So just remove it.
