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

This patchset is dependent on "[0/3] wifi: ath12k: Refactor the hardware recovery procedures"

 v2:
