The old nl80211 testmode is no longer useful in iwlwifi,
we're moving towards a new model internally and there's
no open tool to use it, so remove it.

There are a number of parameters that aren't really hardware
specific but rather define how the DVM firmware is used.
Move these into the DVM configuration.

Until now we didn't handle properly the FLUSH ampdu action
coming from mac80211. This could result in SCD queue leak:
mac80211 would STOP_FLUSH an AMPDU Tx session and remove
the station. If we had still packets on the ring, we
wouldn't deallocate the SCD queue and wait for it to be
empty.
The indication of the queue being empty comes from the Tx
response flow which relies on the tid_data structure. The
problem is that this structure has been cleared when the
station has been removed.
In order to solve this issue, block in the STOP_FLUSH
ampdu_action until the SCD queue is flushed, and only then,
let mac80211 move forward to remove the station.
iwlagn_txfifo_flush had to be enhanced to allow this.
The bug fixed here caused the "txq_id mismatch: 12 0" print.

Many platforms have issues processing a wakeup signal
while they're still suspending, and will ignore it.
Since our device thinks it woke the platform, and the
platform ignored the signal, it will sleep without
WoWLAN being enabled as the device disables WoWLAN
when having woken the platform.
Resolve this by making the device wait for 10 seconds
after getting the suspend signal before waking up the
platform.

There is a race between the restart flow and the workers.
The workers are cancelled after the fw is already killed
and might send HCMD when there is fw to handle them.
Simply check that there is a fw to which the HCMD can be
sent before actually sending it.

Since we will have several forms of NVM (EEPROM, OTP, etc.)
and they will have different layouts, make the parsed data
more generic. This allows functional code to be independent
of a specific layout.
Also change some variables and function names from having
"eeprom" to "nvm" in their name.

The flush_control parameter to iwlagn_txfifo_flush
is passed as an internal value (context flags) and
then sent to the device, that can't be right.
Fix the confusion by removing the parameter, always
use IWL_DROP_ALL that is redefined according to the
firmware API in the flush control.

The flush command really flushes queues, not
FIFOs, and the first 32 bits indicate the
queues to flush, not FIFOs. Change the command
accordingly.

The EEPROM reading/parsing code is all mixed in
the driver today, and the EEPROM is parsed only
when we access data from it. This is problematic
because the NVM needs to be parsed and that is
independent of reading it. Also, the NVM format
for new devices will be different and probably
require a new parser.
Therefore refactor the reading and parsing and
create two independent components. Reading the
EEPROM requires direct hardware accesses and
therefore access to the transport, but parsing
is independent and can be done on an NVM blob.

Since we're working on another mode/driver
inside iwlwifi, move the current one into a
subdirectory to more cleanly separate the
code. While at it, rename all the files.
