cc9bdcf2a4 ASoC: rcar: fix 'const static' variables
When building with 'make W=1', we get a harmless warning about
slightly incorrect prototypes in the rcar audio driver:

sound/soc/sh/rcar/gen.c:209:2: error: 'static' is not at beginning of declaration [-Werror=old-style-declaration]

This changes the 'const static' to 'static const' as it should be.

de1965159a rcar: src: skip disabled-SRC nodes
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 rsnd_mod_call is counting its calling count to avoid unbalanced
function pair calling for error cases (ex init <-> quit).
SSI parent is now controlled as "mod" on current rsnd driver. Because of
this reason, SSI .remove function will be called twice if it was used as
SSI parent when user tried unbind. But probe/remove pair were not

eed76bb811 ASoC: rsnd: add rsnd_runtime_channel_xxx()
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.
This patch adds new rsnd_runtime_channel_xxx() which is caring
CTU/Multi SSI.
