The SDCA spec defines a 'selected_mode' control which can override
the 'detected_mode' reported by hardware.
This is useful for platform integration as well as in cases
where the hardware(e.g. 3.5mm jack cable) is not able to accurately detect the jack type.

Driver in its update status callback stores Soundwire device status in
state container but it never uses it later. Simplify the code a bit.

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.

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.

The DAPM event and mixer control could mute/unmute the capture directly.
That will be confused that capture still works if the user settings is unmute before the capture.
Therefore, this patch uses the variables to record the capture switch status of DAPM and mixer.
