Before, BUSIF which is needed for DMA transfer was automatically handled
via SSI, but it cared BUSIF0 only.
Now, rsnd driver can handle BUSIF0-7 (= for Gen3) BUSIF0-3 (= for Gen2)
via SSIU, and it is keeping compatibility.
Thus, BUSIF0 settings via SSI had been kept to avoid git merge timing
issue / git bisect issue, but it is no longer needed.
This patch removes it.

KingFisher has pcm3168 sound codec. This patch enables it.
Because pcm3168 can't handle symmetric channel on playback/
capture, we need to handle it as different DAI.

This patch adds missing ULCB HDMI sound support.

ULCB can use daughter board which is called as KingFisher.
It has extra sound interface, thus we want to use it.
But, basically, ALSA SoC can't use Multiple sound card with single
CPU sound interface (= SSI). Thus we need to use Single Sound Card
with multiple DAI interface.

To be easy to expand ULCB sound card on KingFisher, it is better to
use multi-dai-link style sound card on ULCB sound DT.

Now, "simple-audio-card" / "audio-graph-card" both can support
multi-dai-link style, but HDMI sound support (which is not yet supported
on ULCB) needs "audio-graph-card".
Using audio-graph-card is better selection.
This patch exchange current sound card to use it.

As of commit 6d2ca852 ("dt-bindings: display: renesas: Deprecate
LVDS support in the DU bindings"), the internal LVDS encoder has DT
bindings separate from the DU.  The device trees for all R-Car H3 and
M3-W development boards were ported over to the new model, but
Salvator-XS boards equipped with an R-Car M3-W SoC were forgotten.
