audio: perf: enable dsp clock for performance measurement

previously, performance measurement based on platform clock, source clock is 38.4mhz, for better align with CPC calculation, change clock to dsp clock, this will be done through enable config: CONFIG_TIMING_FUNCTIONS, and this config only be used with perf_cnt header file, so this change only have impact on performance build.
