ASoC: SOF: Add support ctx_save with IPC4
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The context save functionality with IPC4 is triggered by sending a message to the firmware about the pending power down of the primary core by the host. In order to have this functionality implemented in a clean way we need to introduce a new IPC level PM ops for core state management and use that instead of open coding IPC messages here and there. The first patch updates the ctx store/ctx_restore documentation to clarify that they are optional.
