Adjust and add structs, fields, functions to make more modern versions
of LinuxKPI based wireless drivers (based on wireless-testing (
wt-2023-06-09, wt-2023-07-24, and later)) compile.
Some of these changes can only be applied once all drivers get
updated to not break the old versions currently in the tree.
Mark those changes with __FOR_LATER_DRV_UPDATE for now and flip the
switch at a later point.
