dfe1c7143a topology: use ATTRIBUTE_UNUSED instead remove argument name
We need to support older compilers than GCC 11.

feb9c4cdec reshuffle included files to include config.h as first
config.h may contain defines like _FILE_OFFSET_BITS which influence
the system wide include files (off_t types, open -> open64 function
usage etc.).

df3da091cc topology: nhlt: intel: add support for ssp blob ver 1.5
Ssp plugin had already a definition for newer nhlt blob version 1.5.
Add support to generate that instead of legacy blob. Never blob can be
generated by adding "version" field in SSP dai topology2 definition and
setting it to lower 16 bits of SSP_BLOB_VER_1_5 (0xee000105) -> 0x105
i.e 8 bits for major and 8 bits for minor version.

SSP."0" {
	id              0
	dai_index       0
	direction       "duplex"
	name            NoCodec-0
	version         0x105
}

1ad140f641 topology: plugins: nhlt: add ssp aux controls
Intel ssp blob can have auxiliary controls catenated as tlv array at the
end of its "normal" data blob. These are needed in some platforms for
example to enable hardware clocks earlier than streaming starts.

In topology the auxiliary data classes are embedded into hw_config and
can be instantiated like:

Object.Base.hw_config."SSP0_0" {
	id              0
	mclk_freq       38400000
	bclk_freq       256000
	tdm_slot_width  16
	format          "DSP_A"
	bclk            "codec_provider"
	fsync           "codec_provider"
	fsync_freq      16000

	Object.Base.mn_config."MN_0" {
		m_div   100
		n_div   200
	}

	Object.Base.clk_config."CLK_0" {
		clock_warm_up          1
		mclk                   2
		warm_up_ovr            3
		clock_stop_delay       4
		keep_running           5
		clock_stop_ovr         6
	}
}

f9e6010d5e topology: plugins - add Intel nhlt encoder plugin
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"
