ASoC: rt-sdw*: add __func__ to all error logs

The drivers for Realtek SoundWire codecs use similar logs, which is
problematic to analyze problems reported by CI tools, e.g. "Failed to
get private value: 752001 => 0000 ret=-5". It's not uncommon to have
several Realtek devices on the same platform, having the same log
thrown makes support difficult.

This patch adds __func__ to all error logs which didn't already
include it.

No functionality change, only error logs are modified.

an LDO1 EN descriptor too, if they so desire by putting

ASoC: rt5682-sdw: enable pm_runtime in probe, keep status as 'suspended'

This patch suggests enabling pm_runtime during the probe, but marking the
device as 'active' only after it is enumerated. That will force a
dependency between the card and the codec, pm_runtime_get_sync() will
have to wait for the codec device to resume and hence implicitly wait
for the enumeration/initialization to be completed. In the nominal
case where the codec device is already active the get_sync() would
only perform a ref-count increase.

The changes are directly inspired by RT711 and RT711-sdca changes.

ASoC: rt5682: Use a maple tree based register cache

regmap has introduced a maple tree based register cache which makes use of
this more advanced data structure which has been added to the kernel
recently. Maple trees are much flatter than rbtrees, meaning that they do
not grow to such depths when the register map is sparse which makes access
a bit more efficient. The maple tree cache type is still a bit of a work
in progress but should be effective for some devices already.

RT5682 seems like a good candidate for maple tree. It only supports single
register read/write operations so will gain minimal benefit from storing
the register data in device native format like rbtree does (none for
SoundWire) and has some sparsity in the register map which is a good fit
for maple tree.

Convert to use maple tree. There should be little if any visible difference
at runtime.

ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWire

The HDAudio ASoC support relies on the set_tdm_slots() helper to store
the HDaudio stream tag in the tx_mask. This only works because of the
pre-existing order in soc-pcm.c, where the hw_params() is handled for
codec_dais *before* cpu_dais. When the order is reversed, the
stream_tag is used as a mask in the codec fixup functions:

/* fixup params based on TDM slot masks */
if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK &&
codec_dai->tx_mask)
soc_pcm_codec_params_fixup(&codec_params,
codec_dai->tx_mask);

As a result of this confusion, the codec_params_fixup() ends-up
generating bad channel masks, depending on what stream_tag was
allocated.

We could add a flag to state that the tx_mask is really not a mask,
but it would be quite ugly to persist in overloading concepts.

Instead, this patch suggests a more generic get/set 'stream' API based
on the existing model for SoundWire. We can expand the concept to
store 'stream' opaque information that is specific to different DAI
types. In the case of HDAudio DAIs, we only need to store a stream tag
as an unsigned char pointer. The TDM rx_ and tx_masks should really
only be used to store masks.

Rename get_sdw_stream/set_sdw_stream callbacks and helpers as
get_stream/set_stream. No functionality change beyond the rename.

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.

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: codecs: rt*-sdw: don't assign slave_ops

The SoundWire bus core already assigns the slave ops, no need to set
them a second time manually in each driver.

ASoC: rt5682-sdw: fix 'defined but not used' pm functions

Gcc reports the following warnings:

sound/soc/codecs/rt5682-sdw.c:286:12: warning: 'rt5682_dev_resume'
defined but not used [-Wunused-function]
static int rt5682_dev_resume(struct device *dev)
