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.
