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.
