[PATCH wireless-next 0/2] wifi: remove 5/10 MHz channel support

[Johannes Berg <johannes@sipsolutions.net>]

We had this discussion last about three years ago and nothing changed,
nobody cares about this code and it's de-facto unusable since the AP
side exists but not client, IBSS sort of exists but can't scan for any
networks, etc. It only exists to attract syzbot attention, and with
all attention going to UHR (WiFi 8), NAN, sensing/ranging, etc. I don't
see any of this changing.

Remove it. We can always put things back if anyone _really_ needs it
(and can actually use it), but I'd expect them to help maintain it as
well then.
