Bjoern A. Zeeb d964b9d8ed LinuxKPI: 802.11: adjustments for v6.11 iwlwifi, rtw88 and rtw89 
Bring ing the LinuxKPI 802.11 compat bits which are not altering
the mac80211 ops KPI.

* Add various functions for driver updates.
* Add functions (some compat code to I assume cleanup some
  mac80211 ops) emulating chanctx changes doing (*config) updates.
* Adjust structs and defines.
* Deal with an enum growing more than 32 bits in printf.
* Add a mtx to struct wiphy which is exposed to the drivers.
  Handle initialization and destruction for now.
* Implementation of wiphy_work and wiphy_delayed_work.
* Set was_assoc for deassoc/deauth in prep_tx_info.
