ASoC: rt5682: Convert to use GPIO descriptors
Convert the RT5682 to use GPIO descriptors and drop the
legacy GPIO headers.

We remove the global GPIO number from the platform data,
but it is still possible to create board files using GPIO
descriptor tables, if desired.

Make sure to make sure SDW devices can associate with
an LDO1 EN descriptor too, if they so desire by putting
the lookup into the common code.

ASoC: rt5682: Add a property for DMIC delay
The patch adds a property for DMIC delay (ms) to avoid pop noise and
changes the default delay setting.

ASoC: rt5682: Add a property for DMIC clock rate
The patch adds a property for DMIC clock rate (hz) and changes the
default to the common optimize DMIC clock rate.

ASoC: rt5682: Add CCF usage for providing I2S clks
There is a need to use RT5682 as DAI clock master for other codecs
within a platform, which means that the DAI clocks are required to
remain, regardless of whether the RT5682 is actually running
playback/capture.

The RT5682 CCF basic functions are implemented almost by the existing
internal functions and asoc apis. It needs a clk provider (rt5682 mclk)
to generate the bclk and wclk outputs.

The RT5682 CCF supports and restricts as below:
1. Fmt of DAI-AIF1 must be configured to master before using CCF.
2. Only accept a 48MHz clk as the clk provider.
3. Only provide a 48kHz wclk and a set of multiples of wclk as bclk.

There are some temporary limitations in this patch until a better
implementation.

ASoC: rt5682: improve the sensitivity of push button
The sensitivity could improve by decreasing the HW debounce time
and reduce the delay time of workequeue.
This patch added a device property for HW debounce time control.
We could change this value to tune the sensitivity of push button.
