Sugar Zhang d5a8a6f035 FROMGIT: ASoC: rockchip: Use generic dmaengine code 
This reverts commit 75b31192fe.

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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
