Kuninori Morimoto Feb. 18, 2025, 1:14 a.m. UTC 
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.

Separate it and took DPCM / Codec2Codec connection part.

+ * "compatible" on each test-component. see below
+ *

+ * Below sample doesn't use "format" property,
