ASoC: SOF: ipc4/Intel: Support for firmware exception
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
When a firmware crashes it creats a panic information into a telemetry
slot. The panic format is defined by Zephyr, includes stack and
additional information to help to identify the reason for the crash.
Part of the firmware exception handling the firmware also sends an
EXCEPTION_CAUGHT notification.
This series implements the kernel side handling of the exception: print
information into the kernel log export the whole telemetry slot to user
space for tools extract additional information from the panic dump.
