ath10k-ct: switch to driver version 5.8

Since we are using mac80211 5.8, let's also switch the ath10k-ct driver
to the new 5.8 version.

Modify patches so they patch the new ath10k-ct driver version.
Adapt 164-ath10k-commit-rates-from-mac80211.patch.
Drop upstreamed 205-ath10k-Add-NL80211_EXT_FEATURE_AQL-flag.patch.

Drop the other options for CT_KVER from the comment, as it is incorrect
and there are too many versions to sum up and maintain there.

Runtime-tested on ath79 (D-Link DAP-2695-A1, TP-Link EAP245-v3).
