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.

ASoC: rt715-sdca: 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: SoundWire codecs: make regmap cache-only in probe

The SoundWire bus may start after the probe where the SoundWire ASoC
components are registered. This creates a time window where the card
can be created and the registers be accessed.

As discussed on the mailing list, we can't really control when codecs
are enumerated and initialized, but we can make sure the access to the
codecs is cached until the hardware is accessible.

This patch configures regcache_cache_only() with a 'true' parameter in
the probe function, and a 'false' parameter in the io_init routine.

The rt5682 is handled through a different patch due to its specific
cache handling.

ASoC: codecs: rt715-sdca: simplify set_stream

Using a dynamic allocation to store a single pointer is not very
efficient/useful.

Worse, the memory is released in the SoundWire stream.c file, but
still accessed in the DAI shutdown, leading to kmemleak reports.

And last the API requires the previous stream information to be
cleared when the argument is NULL.

Simplify the code to address all 3 problems.

ASoC: rt715-sdca: Add endianness flag in snd_soc_component_driver

The endianness flag is used on the CODEC side to specify an
ambivalence to endian, typically because it is lost over the hardware
link. This device receives audio over a SoundWire DAI and as such
should have endianness applied.

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: rt715-sdca-sdw: use first_hw_init flag on resume

The intent of the status check on resume was to verify if a SoundWire
peripheral reported ATTACHED before waiting for the initialization to
complete. This is required to avoid timeouts that will happen with
'ghost' devices that are exposed in the platform firmware but are not
populated in hardware.

Unfortunately we used 'hw_init' instead of 'first_hw_init'. Due to
another error, the resume operation never timed out, but the volume
settings were not properly restored.

This patch renames the status flag to 'first_hw_init' for consistency
with other drivers (was 'first_init')
