So far, the formatters have been reset/enabled using the .prepare()
callback. This was done in this callback because walking the formatters use
a mutex so it could not be done in .trigger(), which is atomic by default.

It turns out there is a problem on capture path of the AXG series.
The FIFO may get out of sync with the TDM decoder if the IP are not enabled
in a specific order. The FIFO must be enabled before the formatter starts
producing data. IOW, we must deal with FE before the BE. The .prepare()
callback is called on the BEs before the FE so it is not OK for the AXG.

The .trigger() callback order can be configured, and it deals with the FE
before the BEs by default. To solve our problem, we just need to start and
stop the formatters from the .trigger() callback. It is OK do so now that
the links have been made 'nonatomic' in the card driver.

Non atomic operations need to be performed in the trigger callback
of the TDM interfaces. Those are BEs but what matters is the nonatomic
flag of the FE in the DPCM context. Just set nonatomic for everything so,
at least, it is clear.

This reverts commit 75b31192.

The original purpose of customized pcm was to config prealloc buffer size
flexibly. but, we can do the same thing by soc-generic-dmaengine-pcm.

And the generic one can generated the better config by querying DMA
capabilities from dmaengine driver rather than the Hard-Coded one.

e.g.

the customized one:

  static const struct snd_pcm_hardware snd_rockchip_hardware = {
         .info                   = SNDRV_PCM_INFO_MMAP |
                                   SNDRV_PCM_INFO_MMAP_VALID |
                                   SNDRV_PCM_INFO_PAUSE |
                                   SNDRV_PCM_INFO_RESUME |
                                   SNDRV_PCM_INFO_INTERLEAVED,
  ...

the generic one:

  ret = dma_get_slave_caps(chan, &dma_caps);
  if (ret == 0) {
          if (dma_caps.cmd_pause && dma_caps.cmd_resume)
                  hw.info |= SNDRV_PCM_INFO_PAUSE | SNDRV_PCM_INFO_RESUME;
          if (dma_caps.residue_granularity <= DMA_RESIDUE_GRANULARITY_SEGMENT)
                  hw.info |= SNDRV_PCM_INFO_BATCH;
  ...

So, let's revert back to use the generic dmaengine pcm.

During development of V5 of the i2s-tdm patch series, I replaced
the atomic refcount with a regular integer, as it was only ever
accessed within a spinlock.

Foolishly, I got the semantics of atomic_dec_and_test wrong, which
resulted in a test for 0 actually becoming a test for >0.

The result was that setting the audio frequency broke; switching
from 44100 Hz audio playback to 96000 Hz audio playback would
garble the sound most unpleasantly.

Fix this by checking for --refcount == 0, which is what it should
have been all along.

Since commit 430a67f9 ("block, bfq: merge bursts of newly-created
queues"), BFQ maintains a per-group pointer to the last bfq_queue
created. If such a queue, say bfqq, happens to move to a different
group, then bfqq is no more a valid last bfq_queue created for its
previous group. That pointer must then be cleared. Not resetting such
a pointer may also cause UAF, if bfqq happens to also be freed after
being moved to a different group. This commit performs this missing
reset. As such it fixes commit 430a67f9 ("block, bfq: merge bursts
of newly-created queues").

Such a missing reset is most likely the cause of the crash reported in [1].
With some analysis, we found that this crash was due to the
above UAF. And such UAF did go away with this commit applied [1].

Anyway, before this commit, that crash happened to be triggered in
conjunction with commit 2d52c58b ("block, bfq: honor already-setup
queue merges"). The latter was then reverted by commit ebc69e89
("Revert "block, bfq: honor already-setup queue merges""). Yet commit
2d52c58b ("block, bfq: honor already-setup queue merges") contains
no error related with the above UAF, and can then be restored.
