In ini debug TLVs bit 24 is set. The driver relies on it in the memory
allocation for the debug configuration. This implementation is
problematic in case of a new debug TLV that is not supported yet is added
and uses bit 24. In such a scenario the driver allocate space without
using it which causes errors in the apply point enabling flow.

Solve it by explicitly checking if a given TLV is part of the list of
the supported ini debug TLVs.

The FTM new API uses API TLV bit 15. The driver mistakenly uses
this bit for beacon filter API, although no TLV was assigned for
the beacon filter API. For now, make beacon filter use bit 16
instead (not set by the fw anyway). Once a TLV is assigned to the
beacon filter API it should be updated.

Add new API and TLV for the ability to send commands in the beginning
and end of reset flow.

The full flow of recovery is:

1. While loading FW, get address (from the TLV) of target buffer
   to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.

The main use of the recovery flow is for support in PN/SN recovery
when offloaded

Newer firmware versions (such as iwlwifi-8000C-34.ucode) have
introduced an API change in the SCAN_REQ_UMAC command that is not

not work properly, causing a command timeout.

Fix this by adding a TLV that tells the driver that the new API is in

(e.g. iwlwifi-8000C-31.ucode), so we can't send it to older versions
(such as iwlwifi-8000C-27.ucode).

To fix this, check for a new bit in the FW capabilities TLV that tells
when the command is supported.

Note that the current version of -31.ucode in linux-firmware.git
(31.532993.0) does not have this capability bit set, so the LED won't
work, even though this version should support it.  But we will update
