`strncpy` is deprecated for use on NUL-terminated destination strings
[1].
A suitable replacement is `strscpy` [2].
There are some hopes that someday the `strncpy` api could be ripped out
due to the vast number of suitable replacements (strscpy, strscpy_pad,
strtomem, strtomem_pad, strlcpy) [1].

Add callback to handle loading of kcontrol and linking it to active
widget. In order to link kcontrol to specific modules add additional
field to module data, as well as specify control id in kcontrol data.

Introduce avs_suspend_standby() and avs_resume_standby() to support S0IX
streaming. The AudioDSP is not shutdown during such scenario and the PCI
device is armed for possible wake operation through an audio event.
As capability for a stream to be active during low power S0 is based off
of ->ignore_suspend, adjust the field's value according to platform
capabilities if needed.

For formatted port - ssp%d - descriptions to have an effect, copier
module templates need to be updated with specified port value. This
value is later propagated to the firmware when module instances are
being instantiated.

Each stream in AVS is represented by FE and BE domain. FE path stands
for HOST part of the stream while BE stands for LINK (hardware) one.
While BE portion is interface specific, FE is not. Handle all standard
DAI operations to implement FE part of the stream.

Allow topology to specify formatted strings so machine board's
predefined ->link_mask can be used to specify SSP port number
automatically.
This is done to help reduce the amount of topology files as many I2S
configurations contain codec of the same type with little to no
differences in number of scenarios supported - the only difference being
the port number codec is connected to.

Path template is similar to path description found in skylake-driver
and it describes how given path shall look like in runtime - number of
modules and pipelines that shape it and how they are laid out. It is
tied to DAPM widget's (representing either a FE or a BE) private data.
Depending on the number of audio formats supported, each path template
may carry one or more descriptions of given path. During runtime, when
audio format is known, description matching said format is selected and
used when instantiating path on ADSP firmware side through IPCs.
Add parsing helpers to support loading such information from the
topology file.

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.
