ASoC: SOF: ipc4-control: Implement control update for switch/enum controls

Implement the sof_ipc_tplg_control_ops.update function to support a control
change notification from the firmware on switch or enum control types.

Based on the module notification message content, look up the swidget, then
the scontrol which was the source of the notification then if the message
contains the changed values update the cached values.
If only a notification without values received, marked the control as dirty
and on next read access fetch the new values from the firmware.

ASoC: SOF: ipc4-topology: Correct data structures for the GAIN module

Move the base_cfg to struct sof_ipc4_gain_data. This struct
describes the message payload passed to the firmware via the mailbox.

It is not wise to be 'clever' and try to use the first part of a struct
as IPC message without marking the message section as packed and aligned.

ASoC: sof: Improve sof_ipc4_bytes_ext_put function

The function is improved in the way that if the firmware returns a
validation error on the newly sent bytes, then the kernel will
automatically restore to the old bytes value for a given kcontrol.

This way, if the firmware rejects a data blob then the kernel will also
reject it, instead of saving it for the next suspend/resume cycle. The
old behaviour is that the kernel would save it anyway and on next
firmware boot it would apply the previously-rejected configuration,
leading to errors during playback.

Additionally, the function also saves previously validated
configurations, so that if the firmware does end up rejecting a new
bytes value the kernel can send an old, previously-valid configuration.

ASoC: SOF: ipc4-control: Return on error in sof_ipc4_widget_kcontrol_setup()

The patch adding the bytes control support moved the error check outside
of the list_for_each_entry() which was not correct as at the end of the
list_for_each_entry() the scontrol will no longer point where the error
happened, but it to the list head.

Restore the original logic and return on the first error with the error
code.

ASoC: SOF: ipc4-control: Add support for bytes control get and put

Add support for bytes control by implementing bytes_get/put and
bytes_ext_get/put and blobs with either module init instance or
large config type.

For module init instance type the put will only update the stored
configuration blob and it is going to be taken into use next time the
module is (re-)initialized.

Large config type of blobs are sent to the firmware whenever the DSP is
powered up.

ASoC: SOF: IPC4: update gain ipc msg definition to align with fw

Recent firmware changes modified the curve duration from 32 to 64 bits,
which breaks volume ramps. A simple solution would be to change the
definition, but unfortunately the ASoC topology framework only supports
up to 32 bit tokens.

This patch suggests breaking the 64 bit value in low and high parts, with
only the low-part extracted from topology and high-part only zeroes. Since
the curve duration is represented in hundred of nanoseconds, we can still
represent a 400s ramp, which is just fine. The defacto ABI change has no
effect on existing users since the IPC4 firmware has not been released just
yet.

ASoC: SOF: Protect swidget->use_count with mutex for kcontrol access race

The use_count of the swidget is protect by ALSA core PCM locking with the
exception when an associated kcontrol is changed.

It has been observed that a rightly timed kcontrol access during stream
stop can result of an attempt to send a control update to a widget which
has been freed up between the check of the use_count and the message
sending.

We need to protect the entire sof_widget_setup() and sof_widget_free()
execution to make it safe to rely on the use_count.
Move the code under an _unlocked() function and use a mutex to protect
the execution of the functions for concurrency.
On the control path we need to use the lock only for the kcontrol access,
the widget_kcontrol_setup() op is called with the lock already held.
