tools arm64: Import cputype.h
Bring-in the kernel's arch/arm64/include/asm/cputype.h into tools/ for arm64 to make use of all the core-type definitions in perf. Replace sysreg.h with the version already imported into tools/. Committer notes: Added an entry to tools/perf/check-headers.sh, so that we get notified when the original file in the kernel sources gets modified. Tester notes: LGTM. I did the testing on both my x86 and Arm64 platforms, thanks for the fixing up.
