Currently, the driver does not support single/multi link operation in 11be
mode. Also, each link/radio gets registered as a separate wiphy through
mac80211. In order to support multi link operation (MLO), the current
separate wiphy registration approach brings a lot of complexity in cfg80211
and mac80211, such as synchronization across the multiple wiphy/hw.
Determining the compatibility of the hw across multiple wiphy/hw is another
challenge for userspace. To reduce these complexities in
userspace/cfg80211/mac80211, need to move from the multi wiphy model to a
single wiphy model. To support the single wiphy registration, we have to
decouple the wiphy/mac80211 hw data from the link/radio (ar) structure. So
refactor the MAC helper functions.
