I know, right?! :/

So upon further investigation this seems to be unrelated to the patch.
Meaning that I can't reliably get the ath9k device to work again by
reverting it. And the patch does seem to fix the ath10k device, so I
think that's probably good.

However, the issue with ath9k does seem to be related to ASPM; if I turn
that off in .config, I get the ath9k device back. So we have these
cases:

ASPM disabled:          ath9k, ath10k and mt76 cards all work
ASPM enabled, no patch: only mt76 card works
ASPM enabled + patch:   ath10k and mt76 cards work

So IDK, maybe the ath9k card needs a quirk as well? Or the mvebu board
is just generally flaky?

Erm, it looks like it's never called? I added this:

But 'dmesg | grep called' returns nothing...

I applied your patch on top of latest mac80211-next, which right now is
this commit:
