Subsequent patches will move architectures over to the ARCH_ATOMIC API, after preparing the asm-generic atomic implementations to function with or without ARCH_ATOMIC. As some architectures use the asm-generic implementations exclusively (and don't have a local atomic.h), and to avoid the risk that ARCH_ATOMIC isn't defined in some cases we expect, let's make the ARCH_ATOMIC macro a Kconfig symbol instead, so that we can guarantee it is consistently available where needed. There should be no functional change as a result of this patch.
