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: Disable jack detection interrupt during suspend

The rt5682 driver switches its regmap to cache-only when the
device suspends and back to regular mode on resume. When the
jack detect interrupt fires rt5682_irq() schedules the jack
detect work. This can result in invalid reads from the regmap
in cache-only mode if the work runs before the device has
resumed:

[ 56.245502] rt5682 9-001a: ASoC: error at soc_component_read_no_lock on rt5682.9-001a for register: [0x000000f0] -16

Disable the jack detection interrupt during suspend and
re-enable it on resume. The driver already schedules the
jack detection work on resume, so any state change during
suspend is still handled.

This is essentially the same as commit f7d00a9be147 ("SoC:
rt5682s: Disable jack detection interrupt during suspend")
for the rt5682s.

ASoC: rt5682: Fix deadlock on resume

On resume from suspend the following chain of events can happen:
A rt5682_resume() -> mod_delayed_work() for jack_detect_work
B DAPM sequence starts ( DAPM is locked now)

A1. rt5682_jack_detect_handler() scheduled
- Takes both jdet_mutex and calibrate_mutex
- Calls in to rt5682_headset_detect() which tries to take DAPM lock, it
starts to wait for it as B path took it already.
B1. DAPM sequence reaches the "HP Amp", rt5682_hp_event() tries to take
the jdet_mutex, but it is locked in A1, so it waits.

Deadlock.

To solve the deadlock, drop the jdet_mutex, use the jack_detect_work to do
the jack removal handling, move the dapm lock up one level to protect the
most of the rt5682_jack_detect_handler(), but not the jack reporting as it
might trigger a DAPM sequence.
The rt5682_headset_detect() can be changed to static as well.

ASoC: rt5682-sdw: fix race condition on system suspend

In the initial driver we cancelled deferred work, but there is still a
window of time where a new interrupt could result in new deferred work
executed after the link is disabled, leading to an IO error. While we
did not see this IO error on RT5682-based platforms, the code pattern
is similar to the RT700 case where the IO error was noted, so the fix
is added for consistency.

This patch uses an 'disable_irq_lock' mutex to prevent new interrupts
from happening after the start of the system suspend. The choice of a
mutex v. a spinlock is mainly due to the time required to clear
interrupts, which requires a command to be transmitted by the
SoundWire host IP and acknowledged with an interrupt. The
'interrupt_callback' routine is also not meant to be called from an
interrupt context.

An additional 'disable_irq' flag prevents race conditions where the
status changes before the interrupts are disabled, but the workqueue
handling status changes is scheduled after the completion of the
system suspend. On resume the interrupts are re-enabled already by the
io_init routine so we only clear the flag.

The Fixes tag points to a 5.10 commit, there's no need to propagate
this change to earlier upstream versions.

ASoC: rt5682: split i2c driver into separate module

With SND_SOC_AMD_RV_RT5682_MACH using the i2c version of the
driver, we can easily get a build failure when I2C is built-in
but soundwire is not:

WARNING: unmet direct dependencies detected for SND_SOC_RT5682
Depends on [m]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && (I2C [=y] || SOUNDWIRE [=m]) && (SOUNDWIRE [=m] || !SOUNDWIRE [=m]) && (I2C [=y] || !I2C [=y])
Selected by [y]:
- SND_SOC_AMD_RV_RT5682_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_ACP3x [=y] && I2C [=y] && CROS_EC [=y]

Rework the driver to have three separate modules, with the
main driver just dealing with the common bits and the actual
initialization as part of i2c and sdw specific modules.

The conversion is fairly mechanical to keep it easy to review,
i.e. it moves code around with the minimal required renaming
and changes.

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.
