powerpc/kcsan: Add KCSAN Support
Enable HAVE_ARCH_KCSAN for 64-bit Book3S, permitting use of the kernel concurrency sanitiser through the CONFIG_KCSAN_* kconfig options. KCSAN requires compiler builtins __atomic_* 64-bit values, and so only report support on 64-bit. See documentation in Documentation/dev-tools/kcsan.rst for more information.
