[PATCH] bitops: use safer link explaining the algorithm

[Wolfram Sang]

During review, a concern was raised that the link explaining the
algorithm might get stale. Meanwhile, the site has been archived in the
WayBack machine. So, use their link which is hopefully more stable.

The original patch went upstream via I3C. Yury, do you want to take this
fixup or shall it also go via I3C?
