[RFC PATCH v2 09/10] drivers/perf: Add support for ARMv8.2 Statistical Profiling Extension

The ARMv8.2 architecture introduces the optional Statistical Profiling Extension (SPE). SPE can be used to profile a population of operations in the CPU pipeline after instruction decode. These are either architected instructions (i.e. a dynamic instruction trace) or CPU-specific uops and the
