[Intel-gfx] [PATCH] i915/perf: Start hrtimer only if sampling the OA buffer

SAMPLE_OA parameter enables sampling of OA buffer and results in a call to init the OA buffer which initializes the OA unit head/tail pointers. The OA_EXPONENT parameter controls the periodicity of the OA reports in the OA buffer and results in starting a hrtimer. Before gen12, all use cases requi
