[PATCH] arm_pmu: Delete incorrect cache event mapping for some armv8_pmuv3 events.

[Kulkarni, Ganapatrao]

Perf events L1-dcache-load-misses, L1-dcache-store-misses are mapped to
armv8_pmuv3 (both DT and ACPI) event L1D_CACHE_REFILL. This is incorrect,
since L1D_CACHE_REFILL counts both load and store misses.
Similarly the events L1-dcache-loads, L1-dcache-stores, dTLB-load-misses
and dTLB-loads are wrongly mapped. Hence Deleting all these cache events
from armv8_pmuv3 cache mapping.
