[PATCH 17/43] perf kallsyms: Adopt hex2u64 from tools/perf/util/util.h

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Just removing more stuff from tools/perf/, this is mostly used in the
kallsyms parsing and in places in perf where kallsyms is involved, so we
get it for free there.

With this we reduce a bit more util.h.
