ARM: 7117/1: perf: fix HW_CACHE_* events on Cortex-A9
commit 29a541f6c1f6e4a85628bb86071b9e72c9f8be2c upstream.
Using COHERENT_LINE_{MISS,HIT} for cache misses and references
respectively is completely wrong. Instead, use the L1D events which
are a better and more useful approximation despite ignoring instruction
traffic.
