LinuxKPI: 802.11: fill in more skeleton functions

Some of these are used by mt76 and while I was here and it only was
a handfull I figured I should just clean this all up.

There is one problem in that between 802.11az and 802.11-2024 action
frame formats have changed; I got compile errors from iwlwifi(4) given
I updated them to -2024 so we remain on older versions for the moment.
