ASoC: Intel: avs: clarify Copyright information
For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.

Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

ASoC: Intel: avs: Remove unused IRQ-related code
Most IRQ-related code is duplicated in the driver. Switch to the new
implementation and remove unused members.

While the change is non-trivial, from functional perspective status quo
is achieved.

ASoC: Intel: avs: Abstract IRQ handling
Servicing IPCs on CNL platforms and onward differs from the existing
one. To make room for these, relocate SKL-based platforms specific code
into the skl.c file leaving only the genering irq_handler in the common
code.

ASoC: Intel: avs: Abstract IPC handling
Servicing IPCs on CNL platforms and onward differs from the existing
one. To make room for these, enrich platform descriptor with fields
representing crucial IPC registers and utilize them throughout the code.

While cleaning up device descriptors, reduce the number of code lines by
assigning 'min_fw_version' within a single line.

ASoC: Intel: avs: Move IPC error messages one level down
Code size can be reduced if avs_dsp_send_xxx_msg()s take responsibility
for dumping logs in case of an IPC message failure. In consequence,

ASoC: Intel: avs: D0ix power state support
Audio DSP device supports D0 substates in form of D0ix, allowing for
preserving more power even when device is still considered active (D0).
When entered, certain domains which are not being currently used become
power gated. Entering and leaving D0ix is a complex process and differs
between firmware generations.

Conditions that disallow D0i3 and require immediate D0i0 transition
include but may not be limited to: IPC traffic, firmware tracing and
SRAM I/O. To make D0ix toggling sane, delay D0i3 transition and refresh
the timer each time an IPC is requested.

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
EXCEPTION_CAUGHT notification. IPC timeout is also counted as critical
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.

ASoC: Intel: avs: Inter process communication
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.
