There is a need to use DA7219 as DAI clock master for other codecs
within a system, which means that the DAI clocks are required to
remain, regardless of whether the codec is actually running
playback/capture. To be able to expose control of the DAI clocking
the common clock framework has been employed.
The current implementation adds a simple clock gate for enabling
and disabling the DAI clocks, with no rate control supported
(this is still handled through standard hw_params() functions as
before). If DT is enabled then the clock is added to the OF
providers list, otherwise a clkdev lookup is used.

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.

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.

The I2S controller in the A83T is mostly compatible with the one found
in earlier SoCs such as the A20 and A31. While the documents publicly
available for the A83T do not cover this hardware, the officially
released BSP kernel does have register definitions for it. These were
matched against the A20 user manual. The only difference is the TX FIFO
and interrupt status registers have been swapped around, like what we
have seen with the SPDIF controller.

The property used to specify a GPIO intended for reset is "reset-gpios",
but this binding uses "gpio-reset". It is not compatible with newer
methods used to fetch GPIO pins and to prevent the spread of this error
to other bindings let's rename to be more standard.
We also standardize the pin as active-low, different device trees have
marked the GPIO different ways, luckily the driver currently uses the
low-level GPIO set function which does not respect the active-low flag,
but future changes may change this. This is an active-low reset, mark
it as such.
Lastly, add an example of use for this property.
