ASoC: Intel: avs: Prepare for firmware tracing
Firmware provides its own debug functionality. While coredump is one of
these, traces are the main area of interest. kfifo is enlisted to cache
log data that is being pumped to driver through SRAM. Separate DSP
operations are declared as actual feature implementation differs between
firmware generations.
As log gathering involves usage of IPCs, add all necessary: ENABLE_LOGS
and SYSTEM_TIME.
