Merge series from Herve Codina <herve.codina@bootlin.com>:

The qmc_audio driver supports only audio in interleaved mode.
Non-interleaved mode can be easily supported using several QMC channel
per DAI. In that case, data related to ch0 are sent to (received from)
the first QMC channel, data related to ch1 use the next QMC channel and
so on up to the last channel.

In terms of constraints and settings, the interleaved and
non-interleaved modes are slightly different.

In interleaved mode:
  - The sample size should fit in the number of time-slots available for
    the QMC channel.
  - The number of audio channels should fit in the number of time-slots
    (taking into account the sample size) available for the QMC channel.

In non-interleaved mode:
  - The number of audio channels is the number of available QMC
    channels.
  - Each QMC channel should have the same number of time-slots.
  - The sample size equals the number of time-slots of one QMC channel.

This series add support for the non-interleaved mode in the qmc_audio
driver and is composed of the following parts:
  - Patches 1 and 2: Fix some issues in the qmc_audio
  - Patches 3 to 6: Prepare qmc_audio for the non-interleaved mode
  - Patches 7 and 8: Extend the QMC driver API
  - Patches 9 and 10: The support for non-interleaved mode itself

Compared to the previous iteration, this v2 series mainly improves
qmc_audio_access_is_interleaved().

The current fsl_qmc_audio works in interleaved mode. The audio samples
are interleaved and all data are sent to (received from) one QMC
channel.

Using several QMC channels, non interleaved mode can be easily
supported. In that case, data related to ch0 are sent to (received from)
the first QMC channel, data related to ch1 use the next QMC channel and
so on up to the last channel.

In terms of constraints and settings, the two modes are slightly
different:
- Interleaved mode:
    - The sample size should fit in the number of time-slots available
      for the QMC channel.
    - The number of audio channels should fit in the number of
      time-slots (taking into account the sample size) available for the
      QMC channel.
- Non-interleaved mode:
    - The number of audio channels is the number of available QMC
      channels.
    - Each QMC channel should have the same number of time-slots.
    - The sample size equals the number of time-slots of one QMC
      channel.

Add support for the non-interleaved mode allowing multiple QMC channel
per DAI. The DAI switches in non-interleaved mode when more that one QMC
channel is available.

The QMC audio uses one QMC channel per DAI and uses this QMC channel to
transmit interleaved audio channel samples.

In order to work in non-interleave mode, a QMC audio DAI needs to use
multiple QMC channels. In that case, the DAI maps each QMC channel to
exactly one audio channel.

The current QMC audio driver uses only one QMC channel per DAI. The
context used by QMC channel transfer (read and write) completion
routines does not contains any QMC channel and the only one available
per DAI is used to schedule the next transfer.
This works pretty well with only one QMC channel per DAI.

The future support for non-inlerleave mode will use several QMC channel
per DAI. In that case, QMC channel transfer completion routines need to
identify the QMC channel related to the completion.

In order to fill this lack, even if identifying the current QMC channel
among several QMC channels is not needed for the current code, add one
indirection level and introduce the qmc_dai_chan data structrure.
This structure contains the QMC channel involved in the completion and
refererences to the runtime context (capture and playback) used by the
DAI.

The driver mixes some internal values for channel DMA buffer handling
and PCM pointer handling. In the currently supported interleaved mode,
this mix does not lead to any issues but in order to prepare the
support for the non-interleaved mode, having them clearly separated will
ease the support and avoid additional computation to convert values used
in channel DMA buffer management in values usable for PCM pointer.

Use a specific set of variable for PCM pointer handling and an other set
for channel DMA buffer.

The driver has static 'struct regmap_config', which is then customized
depending on device version.  This works fine, because there should not
be two devices in a system simultaneously and even less likely that such
two devices would have different versions, thus different regmap config.
However code is cleaner and more obvious when static data in the driver
is also const - it serves as a template.

Mark the 'struct regmap_config' as const and duplicate it in the probe()
with kmemdup to allow customizing per detected device variant.
