ASoC: audio-graph-card2-custom-sample: Separate Sample

Browse Source 
Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

audio-graph-card2-custom-sample has many sample connections, but because
ALSA card has number limition for links, it is impossible to have all
samples into 1 ASoC card.

This patch-set separate sample DT into 2 parts, and remove original sample.
Because of this separation, we can see all sample connection via multi Card.

	- for normal
	- for DPCM/Codec2Codec

*
* This sample indicates how to use audio-graph-card2 and its
* custom driver. "audio-graph-card2-custom-sample" is the custome driver
* which is using audio-graph-card2.
*
* You can easily use this sample by adding below line on your DT file,
* and add new CONFIG to your .config.
*
* #include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample.dtsi"
*
* CONFIG_SND_AUDIO_GRAPH_CARD2
* CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
* CONFIG_SND_TEST_COMPONENT
*
*
* You can indicate more detail each device behavior as debug if you modify
* "compatible" on each test-component. see below
*
* test_cpu {
* - compatible = "test-cpu";
* + compatible = "test-cpu-verbose";
* ...
* };
*
* test_codec {
* - compatible = "test-codec";
* + compatible = "test-codec-verbose";
* ...
* };
*
*
* Below sample doesn't use "format" property,
* because test-component driver (test-cpu/test-codec) is supporting
* snd_soc_dai_ops :: .auto_selectable_formats.
* see
* snd_soc_runtime_get_dai_fmt()
* linux/sound/soc/generic/test-component.c :: test_dai_formats

* This sample indicates how to use audio-graph-card2 and its
* custom driver. "audio-graph-card2-custom-sample" is the custome driver
* which is using audio-graph-card2.
*
* You can easily use this sample by adding below line on your DT file,
* and add new CONFIG to your .config.
*
* #include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample1.dtsi"
*
* CONFIG_SND_AUDIO_GRAPH_CARD2
* CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
* CONFIG_SND_TEST_COMPONENT
*
*
* You can indicate more detail each device behavior as debug if you modify
* "compatible" on each test-component. see below
*
* test_cpu {
* - compatible = "test-cpu";
* + compatible = "test-cpu-verbose";
* ...
* };
*
* test_codec {
* - compatible = "test-codec";
* + compatible = "test-codec-verbose";
* ...
* };
*
*
* Below sample doesn't use "format" property,
* because test-component driver (test-cpu/test-codec) is supporting
* snd_soc_dai_ops :: .auto_selectable_formats.
* see
* snd_soc_runtime_get_dai_fmt()
* linux/sound/soc/generic/test-component.c :: test_dai_formats
