4bde10650e wifi: iwlwifi: mvm: fix removing pasn station for responder 
[ Upstream commit ff2687612c ]

In case of MLD operation the station should be removed using the
mld api.

650cadb730 wifi: iwlwifi: mvm: vif preparation for MLO 
In MLO, some fields of iwl_mvm_vif should be defined in the
context of a link. Define a separate structure for these fields and
add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy
code will use only deflink object while MLO related code will use the
corresponding link from the link array.

It follows the strategy applied in mac80211 for introducing MLO
changes.

The below spatch takes care of updating all driver code to access
fields separated into MLD specific data structure via deflink (need
to convert all references to the fields listed in var to deflink.var
and also to take care of calls like iwl_mvm_vif_from_mac80211(vif)->field).

971cbe50e6 iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_id 
Instead of taking the group/command separately, make the function
take a combined command ID. In many cases, this allows us to pass
an existing command ID (e.g. cmd.id), or introduce a new variable
for it, so that we don't use the command ID twice.

This way, we can also use LONG_GROUP implicitly, so we don't need
to spell that out for many commands.

Apart from mvm.h, fw/img.{c,h} changes and some copyright and
indentation updates, this was done with spatch:

f0c8642738 iwlwifi: prefer WIDE_ID() over iwl_cmd_id() 
The order of arguments for iwl_cmd_id() is confusing, and the
version is always 0 and thus a useless argument. Prefer the
WIDE_ID() macro (which needs to be a macro due to use in switch
cases etc.) over the iwl_cmd_id() function.

Obviously done with spatch:

be82ecd3a5 iwlwifi: mvm: add an option to add PASN station 
A FTM responder may do PASN authentication with unassociated stations
to allow secure ranging. In this case, the driver will add an internal
station and install the TK so the FW will accept protected FTM
request frames from this station and will send a protected FTM
response frame.

In addition, the driver needs to configure the HLTK to the FW so
the FW can derive the secure LTF bits. This is left for a later
patch since it is not yet supported by the FW.
