Currently multi-queue is disabled for 22000 devices.

This was since driver isn't supposed to write to prph
registers anymore, and FW needs to configure the RFH.

Now that FW added support for the API - use it and remove
the 22000 multi RX queue disablement.

Bump min API version to avoid compatibility issues.

22560 devices use a new rx_mpdu_desc api.
Update the code to use the new api.
Signed-off-by: NGolan Ben Ami <golan.ben.ami@intel.com>
Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

The rfh for 22560 devices has changed so it supports now
the same arch of using used and free lists, but different
structures to support the last.
Use the new structures, hw dependent, to manage the lists.

bd, the free list, uses the iwl_rx_transfer_desc,
in which the vid is stored in the structs' rbid
field, and the page address in the addr field.

used_bd, the used list, uses the iwl_rx_completion_desc
struct, in which the vid is stored in the structs' rbid
field.

rb_stts, the hw "write" pointer of rx is stored in a
__le16 array, in which each entry represents the write
pointer per queue.

Some features supported by firmware aren't advertised and there is no
way for a driver to query them. This includes e.g. monitor mode details.

Most firmwares support monitor interface but only the latest ones
/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any
reliable detection method for older firmwares (BRCMF_C_MONITOR was tried
but "it only indicates the core part of the stack supports").

Similarly support for tagging monitor frames and building radiotap
headers can't be reliably detected for all firmwares.

This commit adds table that allows mapping features to firmware version.
It adds mappings for 43602a1 and 4366b1 firmwares from
linux-firmware.git. Both were confirmed to be passing monitor frames.
