Remove the control.sta pointer from ieee80211_tx_info to free up
sufficient space in the TX skb control buffer for the upcoming
Transmit Power Control (TPC).
Instead, the pointer is now on the stack in a new control struct
that is passed as a function parameter to the drivers' tx method.

This flow can actually happen due to a corner case in
mac80211: the station is deleted before we get a chance
to reclaim all the packets in flight in AGG queue.
The tid_data for this station is zeroed, and we lose
the match with the Tx queue.

Using the driver_data area in ieee80211_tx_info which
resides in the CB overrides the info->control field.
Add a comment to prevent mistakes.

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.

Different transports will have different needs: New tranports
need headroom for their own use before the Tx cmd. So allocate
the Tx cmd pool in the transport and give it a unique name
based on dev_name.

We need to be able to enable / disable Tx queues in HW
dynamically. So this function is no longer related to AGG
only. It can do the job for any queue, even AC ones. Change
the name to better reflect its role.
Also use the new function to configure the AC / CMD queues
in tx_start.

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.
