man: remove note about CPU controller being unmerged

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0d5936344f30aba0f6ddb92b030cb6a05168efe6

In principle we shouldn't merge this until after 4.15 is released, but the
chances of a revert upstream are low, and in that unlikely scenario we can just
revert this patch, it's a trivial documentation update after all.
