SSI/SRC have under/over flow error handling, and its status is useful
for debuging. But sometimes it might be too much message,
and it might blocks necessity other information.
To avoid such situation, basically this patch indicates interrupt
status debug message if DEBUG was defined, but it will be suppressed
if RSND_DEBUG_NO_IRQ_STATUS was defined.

Current SSI uses PDTA bit which indicates data that Input/Output
data are Right-Aligned. But, 24bit sound should be Left-Aligned
in this HW. Because Linux is using Right-Aligned data, and HW uses
Left-Aligned data, current 24bit data is missing lower 8bit.
To fix this issue, this patch removes PDTA bit, and shift 8bit

The current device tree representation of the R-Car Sample Rate Converters
(SRC) assumes that they are numbered consecutively, starting from 0. Alas,
this is not the case with the R8A7794 SoC where SRC0 isn't present. In
order to keep the existing device trees working, I'm suggesting to use a
disabled node for SRC0. Teach the SRC probe to just skip disabled nodes.

Current SSI is supporting Normal SSI/Multi mode SSI/TDM mode SSI
and its behavior is based on input channels.
This input channel might be converted by CTU,
and SSI needs to be Multi SSI mode / TDM SSI mode if 6ch input
EX) 6ch input, CTU for 2ch, playback
6ch 6ch 2ch 2ch 2ch 2ch
-> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI
EX) 6ch input, no CTU, Multi SSI, playback
6ch 6ch 6ch 6ch 6ch 2ch
-> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI0/SSI1/SSI2
Current driver is using rsnd_get_adinr_chan() / rsnd_get_slot_width()
for this purpose, but it is complicated enough without meaning.

SSI will be used as normal SSI or as clock parent SSI. Therefor,
rsnd driver wants to control SSI and parent SSI separately. Otherwise it
can't use Playback/Capture in the same time.
And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each
mod's status insted of rsnd_mod") before.
OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in
separately. Otherwise, these will be re-initialized during playing if
MUX merges 2 sounds.
Because of these picky reasons, this patch re-defines status on each mod,
and add new parent_ssi_status on rsnd_dai_stream.
