util/amdfwtool/data_parse: fix PMU subprogram/instance ID handling 

The parsing of the PMU binary subprogram and instance numbers only
worked correctly for the cases where the ID in the name in the fw.cfg
file was between 0 and 9, but returned wrong results if it was between a
and f. Switch to using strtol with a base of 16 instead of subtracting
the char '0' from the char in the filename in
find_register_fw_filename_bios_dir to fix this.
