ASoC: dmic: Remove now redundant non_legacy_dai_naming flag
The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

ASoC: dmic: Allow GPIO operations to sleep
If there is a power GPIO provided we control it from DAPM context so there
is no problem with a sleeping GPIO, use the _cansleep() version of the API

ASoC: dmic: introduce mode switch delay
On startup, applications such as PulseAudio or CRAS enable playback or
capture on all PCM devices to verify that configurations are correct,
and close them immediately. For DMICs, this can result in the clock
being turned off very quickly, which may not compatible with internal
state machine transition requirements.

This patch add a mode-switch delay which will prevent the clock from
being turned off without complying with manufacturer timing
specifications. While the DMIC clock may be controlled at a lower level,
be it with hardware or firmware, applying the delay during the
STOP_TRIGGER phase ensures that there is no race condition, e.g. with
the hardware/firmware turning off the clock earlier

ASoC: dmic: add DT module alias
Before this patch the only alias provided by the dmic module is:
alias:          platform:dmic-codec

Device instantiated from DT will not probe automatically with this

After this patch, here is the new alias list:
alias:          platform:dmic-codec
alias:          of:N*T*Cdmic-codecC*
alias:          of:N*T*Cdmic-codec

Now the dmic codec probes automatically when instantiated from DT.

ASoC: dmic: Add optional wakeup delay
On some systems a delay is needed after switching on the clocks, to allow
the output to stabilize and avoid a popping noise at the beginning of
the recording. Add the optional device tree property 'wakeup-delay-ms'
and apply the specified delay after enabling the mic. A blocking delay
can't be applied in dmic_daiops_trigger() since the function is called
in atomic context. Instead use a DAPM event handler to set the enable
GPIO and apply the delay in the handler.

ASoC: dmic: Fix check of return value from read of 'num-channels'
Commit 7fb59e940f ("ASoC: codecs: dmic: Make number of channels
 configurable") introduces an optional property to the device tree
to specify the number of DMIC channels. dmic_codec_probe() uses
of_property_read_u32() to read the DT value, and expects a return
value of -ENOENT when the property does not exist. This expectation
is incorrect, the actual value returned in this case is -EINVAL (see
of_find_property_value_of_size(), which is called under the hood).
Check for -EINVAL instead.

ASoC: codecs: dmic: Make number of channels configurable
The DMIC DAI driver specifies a number of 1 to 8 channels for each DAI.
The actual number of mics can currently not be configured in the device
tree or audio glue, but is derived from the min/max channels of the CPU
and codec DAI. A typical CPU DAI has two or more channels, in consequence
a single mic is treated as a stereo/multi channel device, even though
only one channel carries audio data.

This change adds the option to specify the number of used DMIC channels
in the device tree. When specified this value overwrites the default
channels_max value of 8 in the snd_soc_dai_driver struct of the codec.
