ASoC: SOF: Re-visit firmware state and panic tracking/handling
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
this series will improve how we are tracking the firmware's state to be able to
avoid communication with it when it is not going to answer due to a panic and
we will attempt to force power cycle the DSP to recover at the next runtime
suspend time.
The state handling brings in other improvements on the way the kernel reports
errors and DSP panics to reduce the printed lines for normal users, but at the
same time allowing developers (or for bug reports) to have more precise
information available to track down the issue.
We can now place messages easily in the correct debug level and not bound to the
static ERROR for some of the print chains, causing excess amount or partial
information to be printed, confusing users and machines (CI).
I would have prefered to split this series up, but it was developed together to
achieve a single goal to reduce the noise, but also provide the details we need
to be able to rootcause issues.
