Commit adab66b71abf ("Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS"")
added the config HAVE_64BIT_ALIGNED_ACCESS back into arch/Kconfig with this
revert. In the meantime, commit c9b54d6f362c ("docs: move other kAPI
documents to core-api") changed ./Documentation/unaligned-memory-access.txt
to ./Documentation/core-api/unaligned-memory-access.rst.

Fortunately, ./scripts/documentation-file-ref-check detects this and warns
about this broken reference.

Update the file reference in arch/Kconfig.

Steven, could you pick this fix to your commit or, at least, ack it so that
Jonathan can pick it?
