When the LL/SC atomics are moved out-of-line, they are annotated as
notrace and exported to modules. Ensure we pull in the relevant include
files so that these macros are defined when we need them.

I think we should include <asm/cpucaps.h> since we explicitly use
ARM64_HAS_LSE_ATOMICS here.

Otherwise, I don't see that we need anything else here. With that, or if we
decide that <asm/alternative.h> will always include the definition of cpucaps:
