ASoC: Intel: avs: ICL-based platforms support

Define handlers specific to cAVS 2.0 platforms, that is ICL, JSL and all
other variants based on this very version of AudioDSP architecture. Most
operations are inherited from their predecessors with the major
difference being firmware-logging functionality - IPC request as well as
debug memory windows layout have changed.

ASoC: Intel: avs: Use generic size defines

Instead of using PAGE_SIZE as base of definitions in headers, use
generic size defines. While x86 platforms use 4096 as page size, there
are platforms which use different page sizes. Two of changed defines are
for memory windows on DSP side, which have fixed size independent of
host side page size. Another one is for CLDMA buffer which also doesn't
need to change with page size.

ASoC: Intel: avs: Add data probing requests

Data probing is a cAVS firmware functionality that allows for data
extraction and injection directly from or to DMA stream. To support it,
new functions and types are added. These facilitate communication
with the firmware.

Total of eight IPCs:
- probe module initialization and cleanup
- addition and removal of probe points
- addition and removal of injection DMAs
- dumping list of currently connected probe points or enlisted DMAs

ASoC: Intel: avs: APL-based platforms support

Define handlers specific to cAVS 1.5+ platforms, that is, APL and
similar platforms. These differ from SKL-alike ones in terms of AudioDSP
firmware generation and thus the '+' suffix. Introduciton of IMR,
removal of CLDMA, D0IX support and monolithic-ation of library/module
code are most impactful but are not the only changes brought with this
newer generation. Some generic and 1.5 operations are being re-used to
reduce code size.

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.

ASoC: Intel: avs: Coredump and recovery flow

In rare occasions, under stress conditions or hardware malfunction, DSP
firmware may fail. Software is notified about such situation with

device failure. More often than not, driver can recover from such
situations by performing full reset: killing and restarting ADSP.

ASoC: Intel: avs: Add module management requests

Firmware modules implement processing algorithms. Their lifecycle,
similarly to pipelines is being controlled by IPCs: initialization,
deletion and (un)binding.

Modules can be configured at runtime - runtime parameters. This is done
with help of LARGE_CONFIG IPCs: getter and setter.

Due to firmware limitations, LARGE_CONFIG_GET handler implementation
does not support retrieving payload with size larger than IPC inbox
window size.

Implement the IPC between Intel audio firmware and kernel driver. The
IPC allows transmission of requests, handling of responses as well as
unsolicited (i.e. firmware-generated) notifications.

A subscription mechanism is added to enable different parts of the
driver to register for specific notifications.

The part of the DSP boot process that involves sending ROM message
requires an extra step - must be followed by unstall operation of
MAIN_CORE. All other types of messages do not require such specific
handling, so separate set of functions is provided for sending these.
