ASoC: add Audio Graph Card2 driver
We already have audio-graph-card which is Of-graph base of general
sound card driver.
It is supporting DPCM connection, but was forcibly expanded.
Thus, it is very difficult to add new features on it, for example
Multi CPU/Codec support, Codec2Codec support, etc.
This patch adds more flexible new Audio Graph Card2 driver for it.
audio-graph-card and audio-graph-card2 are similar, but don't have
full compatibility.
Audio Graph Card2 supports very generic connection, but some users
want to have its own settings, for example PLL settings, etc.
For such case, it has customizing support.
In users own driver, it can use Audio Graph Card2 parsing by using
audio_graph2_parse_of(), and doing its own customizing.
Because Audio Graph Card2 is still under experimental stage,
it will indicate such warning when probing, and the DT syntax
might be changed.

ASoC: audio-graph-card2: add DPCM support
This patch adds DPCM support to audio-graph-card2.
It uses "dpcm" node (= D), needs to have routing (= A),
need to indicate both FE/BE at links (= B, C).
dpcm ports@0 is for FE (= B), port@1 is for BE (= C).
remote-endpoint can use both Single/Multi connection.

ASoC: audio-graph-card2: add Codec2Codec support
This patch adds Codec2Codec support to audio-graph-card2.
It can use Codec2Codec but very simple case only for now.
It doesn't have "SWITCH" control yet, thus it start automatically
when it was probed, and can't stop, so far.
Thus it needs to be updated around widgets/routing handling,
and you need to understand that it is under experimental.
Codec has SND_SOC_DAPM_INPUT() (= IN) / SND_SOC_DAPM_OUTPUT(= OUT)
widgets in below case.
It is assuming 2channel, S32_LE format for now.
It needs to be updated, too.
It needs "codec2codec" node (= B), needs to have routing (= A),
need to indicate CPU side at links (= X).
ports@0 is for CPU side (= X), port@1 is Codec side (= Y).
It needs to have "rate" (= C)
