Group onboard mic and headphone mic jack together. Creates association that
will switch between microphone inputs depending on the state of the headphone
jack being connected to a live mic.
Fixes onboard mic not working at all on T520.
Tested on T520, T420.
Suspect X220 needs this too, untested on.

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.

Most likely some non-USB compliant devices will choke on it
sooner or later. Clear stall is strictly speaking not needed.
If the first MIDI command sent or transmitted is lost, this
is not a big problem for us.

o The CP2101 and CP2102 do not support GPIO pin use at all, enforce this.
o Support reading the GPIO status on the second port of the CP2105. More
work is needed before the CP2105 GPIO pins can be used as outputs.

doesn't match the actual hardware queue this frame is queued to.
I'm trying to ensure that the holding buffers are actually being queued
to the same TX queue as the holding buffer that they end up on.
I'm pretty sure this is all correct so if this complains, it'll be due
to some kind of subtle broken-ness that needs fixing.
This is only done for legacy hardware, not EDMA hardware.

recreating the filesystem, check for and output the -i, -k, and -l
options if appropriate.
Note the remaining deficiencies of the -m option in the dumpfs(8)
manual page. Specifically that newfs(8) options -E, -R, -S, and -T
options are not handled and that -p is not useful so is omitted.
Also document that newfs(8) options -n and -r are neither checked
for nor output but should be. The -r flag is needed if the filesystem
uses gjournal(8).
