ASoC: samsung: i2s: Restore support for the secondary PCM
This patch introduces again registration of additional platform device as
we still need it for registering the secondary dmaengine PCM component.

This patch in most part is a revert of changes done in commit
be2c92eb64 ("ASoC: samsung: i2s: Remove virtual device for secondary DAI")

ASoC: samsung: i2s: Convert to single component with multiple DAIs
This patch includes minimal changes as a prerequisite for adding support
for the Exynos secondary I2S interface as second DAI of the I2S component.
Doing it that way allows to avoid problems as indicated in commmit
6b01e0365b1689 ("ASoC: samsung: i2s: disable secondary DAI until it gets fixed")

The samsung_i2s_get_pri_dai() helper added in this patch is temporary and

ASoC: dmaengine: Extend use of chan_names provided in custom DMA config
There are currently two ways to specify custom DMA channel names:
 - through the SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag and
   snd_dmaengine_dai_dma_data data structure,
 - through chan_names field of struct snd_dmaengine_pcm_config.

In order to replace the DAI DMA data method with the custom DMA config
one on non-DT platforms the dmaengine_pcm_new() function is extended
to also consider channel names specified in the custom DMA config.
If both config->chan_names and dma_data->chan_name are provided
the former will be used.

tlv320aic32x4: delay i2c access by 1 ms after hardware reset
As stated in 'TLV320AIC3254 Application Reference Guide' ([1]):

  3.2 Device Startup Lockout Times
    After the TLV320AIC3254 initializes through hardware reset at power-up
    or software reset, the internal registers initialize to default values.
    This initialization takes place within 1ms after pulling the RESET
    signal high. During this initialization phase, no register-read or
    register-write operation should be performed on ADC or DAC coefficient
    buffers. Also, no block within the codec should be powered up during
    the initialization phase.

ASoC: core: don't increase component module refcount unconditionally
The ASoC core has for the longest time increased the module reference
counts, even before the transition to the component model. This is
probably fine on most platforms, but it introduces a deadlock case on
Intel devices with the Skylake and SOF drivers which cannot be removed
due to their reference counts being modified by the core.

In these 2 cases, the PCI or ACPI driver .probe creates a platform
device to let the machine driver .probe register the audio
card. Conversely the PCI or ACPI driver .remove will unregister the
platform device which results in the card being removed by the machine
driver .remove.

With ascii art, this can be represented as

modprobe
snd_soc_skl/
soc-pci-dev/sof-acpci-dev  ----------> pci/acpi probe
       ^                                    |
       |                     ---------------|
       |                    |               |
       |                    V               V
    increase            register        register machine
    refcount            component       platform_device
       ^                                    |
       |                                    |
       |                                    V
    component <----   register card  <---- probe
    probe

The issue is that by playing with the component's module reference
counts during the card registration, it's no longer possible to remove
the module which controls the component. This can be shown, e.g. with
the following error:

root@plb-XPS-13-9350:~# lsmod | grep snd_soc_skl
snd_soc_skl           110592  1

root@plb-XPS-13-9350:~# rmmod snd_soc_skl
rmmod: ERROR: Module snd_soc_skl is in use

Increasing the reference count during the component probe is not
useful. If the PCI/ACPI module is removed, the card will be removed
anyway.

To avoid breaking existing platforms and allowing Intel platforms to
safely deal with module load/unload cases, this patch introduces a
flag which needs to be set during the component initialization. This
is a strictly opt-in capability that should only be used when the
handling of the component module does not require a reference count
increase to prevent removal during use.

Note that this solution is not directly applicable to the legacy
Atom/SST driver, which uses a different device hierarchy. There are
however additional refcount issues which prevent the ACPI driver from
being removed. This is a different issue which would need a different
patch.
