ASoC: SOF: ipc4: Add data struct for module notification message from firmware
With the module notification message the information about the notification
is provided via the mailbox with the sof_ipc4_notify_module_data struct.
It contains the module and instance id of the sender of the notification,
the event_id and optionally additional data which is module and event
specific.
At the same time add definitions to identify ALSA kcontrol change
notification.
These notifications use standardized event_id, modules must follow this if
they support such notifications:
upper 16 bit: 0xA15A as a magic identification value
lower 16 bit: param_id of the changed control
