perf pmu: Change convert_scale from static to global
The function convert_scale() can be used to convert string to unit and scale. For example, s = "6000000000ns"; convert_scale(s, &unit, &scale); unit = "ns", scale = 6000000000. Currently this function is static. This patch renames the function to perf_pmu__convert_scale and changes the function to global. No functional change.
