ASoC: rt5640: Convert to just use GPIO descriptors

The RT5640 driver is already using GPIO descriptors for some
stuff, all that is needed is to convert the remaining LDO1
control line to also use descriptors.

Simplify the code using gpiod_get_optional() and drop the
special "of" parsing function: these descriptors need not
come from device tree and it's optional so hey.

Keep some NULL checks around the GPIO operations even though
gpiolib is essentially NULL-tolerant, because by checking
for whether we have a valid GPIO descriptor or not we can
avoid a 400 ms delay which is great.

ASoC: rt5640: Allow configuration of LOUT to mono differential mode

LOUT output can produce either single-ended stereo signals, or mono

ASoC: rt5640: Add support for boards with an external jack-detect GPIO

Some boards have the codec IRQ hooked-up as normally, so the driver can
still do things like headset vs headphones and button-press detection,
but instead of using one of the JD pins of the codec, an external GPIO
is used to report the jack-presence switch status of the jack.

Add support for this.

ASoC: rt5640: Allow snd_soc_component_set_jack() to override the codec IRQ

On some boards where the firmware/fwnode information is in essence
read-only (x86 + ACPI boards) the i2c_client for the codec may contain
the wrong IRQ or no IRQ at all.

Since we only request the IRQ once snd_soc_component_set_jack() gets
called, allow machine drivers to override the IRQ with the proper one
through the data parameter to snd_soc_component_set_jack().

Some devices don't use the builtin jack-detect but can still benefit
from the mic-bias-current over-current-detection headphones vs
headset detection done by rt5640_detect_headset().

In this case the jack-inserted check done by rt5640_detect_headset()
needs to be done through a GPIO rather then by using the codec's
builtin jack-detect. Add an optional hp_det_gpio parameter and export
rt5640_detect_headset() for use on machines where jack-detect is
handled outside of the codec.

ASoC: rt5640: Add function for enabling DMIC from ACPI probed machine

There is no code enabling DMIC clock in systems that don't provide platform
data for rt5640 after commit 71d97a794301 ("ASoC: rt5640: Use the platform
data for DMIC settings").

I think it's worth to keep this static DMIC clock and alternative data pin
setting during probe time. For making possible to use DMIC from ACPI probed
machine (prior ACPI 5.1 with _DSD) this patch moves DMIC configuration to
new exported rt5640_dmic_enable() that machine drivers can call.

Please note, this patch moves DMIC configuration from i2c probe to codec
probe in case platform data for rt5640 is set.

ASoC: rt5640: Add minimal support for RT5642

We have been using rt5640.c codec driver with RT5642 codec chip before commit
022d21f004c1 ("ASoC: rt5640: add rt5639 support"). That commits starts using
device ID reading in reset register for adding device specific controls and
routes runtime.

Now since device ID appears to be different between RT5640 and RT5642 the
driver doesn't add those controls and routes that are valid also on RT5642.

Fix this by adding a device ID found by debugging and minimal code for
supporting RT5642.
