bebc14db4e iwlwifi: mvm: avoid possible NULL pointer dereference 
When adding a PASN station, the station is added to the list only
if a TK is configured. Otherwise the station pointer should not be
used.

68ad24742f iwlwifi: mvm: responder: allow to set only the HLTK for an associated station 
For secure ranging with an associated station, the driver only needs
to set the HLTK. There is no need to add an internal station for PMF
since the FW will use the existing station which already has the TK
installed.

e80bfd117d iwlwifi: fw: add default value for iwl_fw_lookup_cmd_ver 
For new APIs this avoids checking every return if it's
IWL_FW_CMD_VER_UNKNOWN (99) or it's lower than the new API value

Done with spatch:
-iwl_fw_lookup_cmd_ver(E1, E2, E3)
+iwl_fw_lookup_cmd_ver(E1, E2, E3, IWL_FW_CMD_VER_UNKNOWN)

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.

4af119509a iwlwifi: move API version lookup to common code 
The API version lookup is parsed from a TLV and should be in shared code
make make it reusable across all opmodes.

Also change the function names from mvm to fw, since this is not
mvm-specific anymore.

Additionally, since this function is not just a single line of code, it
shouldn't be inline.  Convert them to actual functions.
