tools: arm64: Add a Makefile for generating sysreg-defs.h
Use a common Makefile for generating sysreg-defs.h, which will soon be
needed by perf and KVM selftests. The naming scheme of the generated
macros is not expected to change, so just refer to the canonical
script/data in the kernel source rather than copying to tools.
