Subject: [PATCH 2/2] doc: re-run features-refresh.sh

Some arch-support.txt are out-of-date.
This also incl. riscv in sg-chain and pte_special tables.

I'm not opposed to this, but I have no idea what it does or why it's in
arch/*/Kconfig. I've added the first patch to next-sg_chain, but I'm going to
re-do the second one as it looks like it batches up a bunch of updates.

Thanks!
