Subject: [PATCH v1 5/5] perf parse-regs: Move out arch specific header from util/perf_regs.h

util/perf_regs.h includes another perf_regs.h:

  #include <perf_regs.h>

Here it includes architecture specific header, for example, if we build
arm64 target, the header tools/perf/arch/arm64/include/perf_regs.h is
included.

We use this implicit way to include architecture specific header, which
is not directive; furthermore, util/perf_regs.c is coupled with the
architecture specific definitions.

This patch moves out arch specific header from util/perf_regs.h for
generalizing the 'util' folder, as a result, the source files in 'arch'
folder explicitly include architecture's perf_regs.h.

Signed-off-by: Leo Yan <leo.yan@...aro.org>
