Subject: [PATCH] tools headers arm64: Fix compilation failure

When build perf tool on x86_64, it reports failure for finding the
header <asm/sysreg.h>:

  In file included from util/arm-spe.c:37:
  util/../../arch/arm64/include/asm/cputype.h:183:10: fatal error: asm/sysreg.h: No such file or directory
    183 | #include <asm/sysreg.h>
        |          ^~~~~~~~~~~~~~
  compilation terminated.

There have no sysreg.h in x86's asm folder, alternatively, this patch
includes the sysreg.h header in the same folder with cputype.h to fix
the compilation failure.

Fixes: 37402d5d061b ("tools headers arm64: Sync arm64's cputype.h with the kernel sources")
