ASoC: Intel: avs: ICCMAX recommendations for ICL+ platforms

For ICL+ platforms to avoid DMI/OPIO L1 entry during the base firmware
load procedure, HW recommends to set LTRP_GB to 95us and start an
additional CAPTURE stream in the background.

Once the load completes, original LTRP_GB value is restored and the
additional stream is released.

ASoC: Intel: avs: Machine board registration

AVS driver operates with granular audio card division in mind.
Super-card approach (e.g.: I2S, DMIC and HDA DAIs combined) is
deprecated in favour of individual cards - one per each device. This
provides necessary dynamism, especially for configurations with number
of codecs present and makes it easier to survive auxiliary devices
failures - one card failing to probe does not prevent others from
succeeding.

All boards spawned by AVS are unregistered on ->remove(). This includes
dummy codecs such as DMIC.

As all machine boards found in sound/soc/intel/boards are irreversibly
tied to 'super-card' approach, new boards are going to be introduced.
This temporarily increases number of boards available under /intel

ASoC: Intel: avs: Path creation and freeing

To implement ASoC PCM operations, DSP path handling is needed. With path
template concept present, information carried by topology file can be
converted into runtime path representation. Each may be composed of
several pipelines and each pipeline can contain a number of processing
modules inside. Number of templates and variants found within topology
may vastly outnumber the total amount of pipelines and modules supported
by AudioDSP firmware simultaneously (in runtime) so none of the IDs are
specified in the topology. These are assigned dynamically when needed
and account for limitations described by FIRMWARE_CONFIG and
HARDWARE_CONFIG basefw parameters.

Paths are created on ->hw_params() and are freed on ->hw_free() ALSA PCM
operations. This choice is based on firmware expectations - need for
complete set of information when attempting to instantiate pipelines and
modules on AudioDSP side. With DMA and audio format provided, search
mechanism tests all path variants available in given path template until
a matching variant is found. Once found, information already available
is combined with all avs_tplg_* pieces pointed by matching path variant.
This finally allows to begin a cascade of IPCs which goal is to reserve
resources and prepare DSP for upcoming audio streaming.

ASoC: Intel: avs: Add topology parsing infrastructure

AVS topology is split into two major parts: dictionaries - found within
ASoC topology manifest - and path templates.

Dictionaries job is to reduce the total amount of memory
occupied by topology elements. Rather than having every pipeline and
module carry its own information, each refers to specific entry in
specific dictionary by provided (from topology file) indexes. In
consequence, most struct avs_tplg_xxx are made out of pointers.

To support the above, range of parsing helpers for all value-types known
to ALSA: uuid, bool, byte, short, word and string are added. Additional
handlers help translate pointer-types and more complex objects such as
audio formats and module base configs.

Path templates are similar to path descriptions found in skylake-driver
and they describe how given path shall look like in runtime - number of
modules and pipelines that shape it and how they are laid out.

ASoC: Intel: avs: General code loading flow

Code loading is a complex procedure and requires combined effort of DMA
and IPCs. With IPCs already in place, lay out ground for specific DMA
transfer operations.

ASoC: Intel: avs: Dynamic firmware resources management

Wrap elementary DSP-core operations and resource control into more
complex handlers. This is done to reduce the number of invocations of
wrapped operations throughout the driver as order of operations matters -
most flows involve register manipulation and IPCs combined.

ASoC: Intel: avs: Firmware resources management utilities

With basefw runtime parameter handlers added, implement utility
functions to ease pipelines and modules allocation. IDA is enlisted to
help with that.

As firmware is modular and multiple binaries can be loaded on-demand
depending on the streaming scenario, custom firmware caching mechanism
is added.

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.

ASoC: Intel: Introduce AVS driver

Declare base structures and core DSP operations for the avs solution.
The base structures describe PCI HDAudio bus device and platform-type
differentiations. First set of operations added controls the lifecycle
of any Audio DSP core: (un)powering, (un)resetting and (un)stalling.
