wifi: iwlwifi: api: link context action in kernel-doc

This is clearer in kernel-doc than spelling out the prefix.
It also lets us generate better tracing data.

Use SPDX tags instead of the long copyright notices. Also cleanup
some duplicate copyright notices and combine the years where possible.

iwlwifi: mvm: properly cancel a session protection for P2P

We need to feed the configuration id to remove session protection
properly.
Remember the conf_id when we add the session protection so that we
can give it back when we want to remove the session protection.
While at it, slightly improve the kernel doc for the conf_id
of the notification.

iwlwifi: mvm: use the new session protection command

The firmware has now a new session protection command.
This new API allows the firmware to manage the protection
needed for association. It'll also remove the event when
the association is complete.

iwlwifi: mvm: Change FW channel info API

Change iwl_fw_channel_info structure so it can have channel number
greater than 255. This is needed for 6 GHz channel numbers.
Change all relevant structs and member accesses accordingly.
The new API is indicated by a TLV capability bit.

iwlwifi: mvm: Fix channel switch for count 0 and 1

It was assumed that apply_time==0 implies immediate scheduling, which is
wrong. Instead, the fw expects the START_IMMEDIATELY flag to be set.
Otherwise, this resulted in 0x3063 assert.
Fix that.
While at it rename the T2_V2_START_IMMEDIATELY to
TE_V2_START_IMMEDIATELY.

iwlwifi: reorganize firmware API

Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new
fw/api/ directory.

While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.
