perf callchain: Separate perf_reg_value function in perf_regs object

Making perf_reg_value function global (formely reg_value), because it's
going to be used globaly across all code providing the dwarf post unwind
feature.

Changing its prototype to be generic:

  -int reg_value(unw_word_t *valp, struct regs_dump *regs, int id)
  +int perf_reg_value(u64 *valp, struct regs_dump *regs, int id);

Changing the valp type from libunwind specific 'unw_word_t' to u64.
