Adrian Chadd 9be82a4209 Be (very) careful about how to add more TX DMA work. 
The list-based DMA engine has the following behaviour:

* When the DMA engine is in the init state, you can write the first
  descriptor address to the QCU TxDP register and it will work.

* Then when it hits the end of the list (ie, it either hits a NULL
  link pointer, OR it hits a descriptor with VEOL set) the QCU
  stops, and the TxDP points to the last descriptor that was transmitted.

* Then when you want to transmit a new frame, you can then either:
  + write the head of the new list into TxDP, or
  + you write the head of the new list into the link pointer of the
    last completed descriptor (ie, where TxDP points), then kick
    TxE to restart transmission on that QCU>

* The hardware then will re-read the descriptor to pick up the link
  pointer and then jump to that.

Now, the quirks:

* If you write a TxDP when there's been no previous TxDP (ie, it's 0),
  it works.

* If you write a TxDP in any other instance, the TxDP write may actually
  fail.  Thus, when you start transmission, it will re-read the last
  transmitted descriptor to get the link pointer, NOT just start a new
  transmission.

So the correct thing to do here is:

* ALWAYS use the holding descriptor (ie, the last transmitted descriptor
  that we've kept safe) and use the link pointer in _THAT_ to transmit
  the next frame.

* NEVER write to the TxDP after you've done the initial write.

* .. also, don't do this whilst you're also resetting the NIC.

With this in mind, the following patch does basically the above.

* Since this encapsulates Sam's issues with the QCU behaviour w/ TDMA,
  kill the TDMA special case and replace it with the above.

* Add a new TXQ flag - PUTRUNNING - which indicates that we've started
  DMA.

* Clear that flag when DMA has been shutdown.

* Ensure that we're not restarting DMA with PUTRUNNING enabled.

* Fix the link pointer logic during TXQ drain - we should always ensure
  the link pointer does point to something if there's a list of frames.
  Having it be NULL as an indication that DMA has finished or during
  a reset causes trouble.

Now, given all of this, i want to nuke axq_link from orbit.  There's now HAL
methods to get and set the link pointer of a descriptor, so what we
should do instead is to update the right link pointer.

* If there's a holding descriptor and an empty TXQ list, set the
  link pointer of said holding descriptor to the new frame.

* If there's a non-empty TXQ list, set the link pointer of the
  last descriptor in the list to the new frame.

* Nuke axq_link from orbit.

Note:

* The AR9380 doesn't need this.  FIFO TX writes are atomic.  As long as
  we don't append to a list of frames that we've already passed to the
  hardware, all of the above doesn't apply.  The holding descriptor stuff
  is still needed to ensure the hardware can re-read a completed
  descriptor to move onto the next one, but we restart DMA by pushing in
  a new FIFO entry into the TX QCU.  That doesn't require any real
  gymnastics.

Tested:

* AR5210, AR5211, AR5212, AR5416, AR9380 - STA mode.
