Subject: [PATCH 00/12] wifi: ath12k: Add single wiphy support

With the introduction of Multi Link Operation (MLO) support in
IEEE802.11be, each EHT AP/non AP interface is capable of
operating with multiple radio links.

cfg80211/mac80211 expects drivers to abstract the communication
between such Multi Link HW and mac80211/cfg80211 since it depends
on different driver/HW implementation. Hence the single wiphy
abstraction with changes in datastructures were introduced in
"wifi: ath12k: Introduce hw abstraction"

This patchset extends the implementation to allow combination
of multiple underlying radios into a single composite hw/wiphy
for registration. Since now multiple radios are represented by
a single wiphy, changes are required in various mac ops that the
driver supports since the driver now needs to learn on how to tunnel
various mac ops properly to a specific radio.

This patchset covers the basic mac80211 ops for an interface bringup
and operation.

Note:
In addition to sanity on single radio QCN9274 and WCN7850
the single wiphy changes are tested over "wifi: ath12k: QCN9274 dualmac bring up"
where multiple radios in the dualmac SoC are combined and tested.

Monitor and hw reconfig support for Single Wiphy will be done in future
patchsets.

This patchset is dependent on "[PATCH 0/2] wifi: ath12k: Introduce hw abstraction"
