Dmic find_modes function was used with same sampling rate for both fifo
a and b parameter calculations. This bug was found in testing two
simultaneous dmic dais in topology. Fix this by introducing a sampling
rate argument for find_modes.

Add Intel nhlt acpi table encoder plugin into topology2.0 processing.
Nhlt internal structure is defined in:
https://01.org/sites/default/files/595976_intel_sst_nhlt.pdf
Nhlt acpi table contain vendor specific binary data blobs that are used
in some Intel dsp platforms for configuring the dmic and ssp hardware.
The function of this code is mainly to generate the vendor specific
binary blobs, but as there is existing nhlt parser code and header in
kernel there's no point of re-inventing the container: just use the
existing nhlt acpi table format. Basically this code is creating similar
nhlt acpi table that you would get from: cat
/sys/firmware/acpi/tables/NHLT
This code will have implementation for dmic and ssp endpoints. Thus the
code will translate the topology dai tokens into vendor specific binary
blobs and pack them into nhlt acpi table. Ssp and dmic code is lifted
from Sound Open Firmware (sof) code base, thus it will have BSD-3
license.
This plugin can be enabled from command line with:
alsatplg -DPREPROCESS_PLUGINS="nhlt" -c foo.conf -p -o bar.tplg
You can also dump the nhlt binary into a file with additional define:
-DNHLT_BIN="nhlt.bin"

Add a simple plugin interface for processing the topology tree. There
can be cases where parts of the topology need to be translated from the
original format into something else. For example one could calculate
some kind of filter coefficients from filter parameters or some other
binary interface parameters from plain text topology tokens.
Mechanism is similar as in alsa-plugins and in the plugin there should
be only 1 function exported of the form:
int _snd_topology_##pluginname##_process (snd_config_t *input, snd_config_t *output)
Input and output parameters are snd_config tree before and after topology2
pre-processing. So the plugin can modify both if needed. There are cases
where the plugin may need to get information from input tree, but make
modifications to the output.
The plugins to be used can be defined in command line with:
alsatplg -DPREPROCESS_PLUGINS="foobar" -c topology.conf -p -o topology.tplg
Multiple plugins should be separated by ":".
Plugins to be used can also be defined with "Define" clause inside the
topology file (but command line takes precedence):
Define {
PREPROCESS_PLUGINS "foobar"
}

With the introduction of variables in the topology files, validation of
attributes values must be done after they are expanded to their defined
values. Also, since valid values for attributes in the class definition
can also be variables, they need to be expanded as well. So, first expand
the attribute values and then check them against expanded valid values.

Remove the call to snd_config_expand_custom() to expand the top-level
input config. And replace it with calls to snd_config_evaluate_string()
for each non-compound config while processing individual objects. This
will allow retreving variable definitions from object attribute values
and global definitions.
Add a new field "current_obj_cfg" to hold the current object config
being pre-processed.
This will facilitate adding simple math expressions for computing
attribute values for objects based on other attributes. For ex: we can
set the expression for buffer size as follows:
buffer_size "$[($in_channels * 48) * 4]"
The buffer_size attribute value will be computed with the attribute
value "in_channels" based on the expression above. So if $in_channels =
2, buffer_size will be evaluated to 384.
Additionally this change also permits computing attribute values based
on previously computed values. For example:
buffer_size "$[($in_channels * 48) * 4]"
dma_buffer_size "$[$buffer_size * 2]"
dma_buffer_size will be computed as 768. Note that the order of
definitions for buffer_size and dma_buffer_size matters because the
evaluation for dma_buffer_size depends on the evaluation of buffer_size.
In order to conform to this, the tplg_object_copy_and_add_param() is
modified to add attribute configs from class config to an object using
snd_config_before() instead of snd_config_add().
With this change, we no longer need to set the auto_attr_updater for
buffer type widget objects. So remove it.

Add a -D switch to be able to pass pre-processor definitions that will
be used to expand arguments in the input config file. This will be
useful to generate multiple topology binaries from the same input config
file with different argument values.
For example: if we had a pipeline config as follows:
Object.Pipeline {
volume-playback.1 {
dynamic_pipeline $DYNAMIC_PIPELINE
}
}
We can define the variable for DYNAMIC_PIPELINE as:
Define {
DYNAMIC_PIPELINE 0
}
And when pre-processing the conf file pass "-D DYNAMIC_PIPELINE=1" to
override the default value for dynamic_pipeline attribute in the input
conf file.
