ASoC: SOF: ipc4/Intel: Support for partial context
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The firmware will be able to only save and restore the context related to
library management.
This means that even without a full context save, the libraries do not
need to be re-loaded to the firmware after second or consecutive boots.
This is reported via the FW_READY notification, where BIT(15) indicates:
0 - the library restore is not done
1 - library restore is done
This bit is only valid if full context save is not enabled, full context
save is by definition saves and restores the library related book-keeping
as well.
Add a new flag to tell the platform code if the libraries have been
restored, no need to reload them after boot.
