arm64: nexus code tidy-up
Make a pass at the various nexus implementations, fixing some very minor style issues, obsolete comments, etc. The method declaration section has become unwieldy in many respects. Attempt to tame it by: - Using generated method typedefs - Grouping methods roughly by category, and then alphabetically. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D38495
