ASoC: codecs: rt711-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: rt711-sdca: fix kernel NULL pointer dereference when IO error
The initial settings will be written before the codec probe function.
But, the rt711->component doesn't be assigned yet.
If IO error happened during initial settings operations, it will cause the kernel panic.
This patch changed component->dev to slave->dev to fix this issue.

ASoC: codecs: rt700/rt711/rt711-sdca: resume bus/codec in .set_jack_detect
The .set_jack_detect() codec component callback is invoked during card
registration, which happens when the machine driver is probed.

The issue is that this callback can race with the bus suspend/resume,
and IO timeouts can happen. This can be reproduced very easily if the
machine driver is 'blacklisted' and manually probed after the bus
suspends. The bus and codec need to be re-initialized using pm_runtime
helpers.

Previous contributions tried to make sure accesses to the bus during
the .set_jack_detect() component callback only happen when the bus is
active. This was done by changing the regcache status on a component
remove. This is however a layering violation, the regcache status
should only be modified on device probe, suspend and resume. The
component probe/remove should not modify how the device regcache is
handled. This solution also didn't handle all the possible race
conditions, and the RT700 headset codec was not handled.

This patch tries to resume the codec device before handling the jack
initializations. In case the codec has not yet been initialized,
pm_runtime may not be enabled yet, so we don't squelch the -EACCES
error code and only stop the jack information. When the codec reports
as attached, the jack initialization will proceed as usual.

ASoC: rt7*-sdw: harden jack_detect_handler
Realtek headset codec drivers typically check if the card is
instantiated before proceeding with the jack detection.

The rt700, rt711 and rt711-sdca are however missing a check on the
card pointer, which can lead to NULL dereferences encountered in
driver bind/unbind tests.

ASoC: rt711-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

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: rt711-sdca-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 RT711-sdca-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 code is slightly different from the other codecs since the
interrupt callback deals with the SDCA interrupts, leading to a much
larger section that's protected by the mutex. The SoundWire interrupt
scheme requires a read after clearing a status, it's not clear from
the specifications what would happen if SDCA interrupts are disabled
in the middle of the sequence, so the entire interrupt status
read/write is kept as is, even if in the end we discard the
information.
