The glue saves stream's private data in front-end dai and then backend
dai can reach them searching backward from sink to source. For capture
stream everything left the same, but searching should be performed from
source to sink.

Hope, I haven't misinterpreted the terminology and codec-glue's behavior
too much.

There are many of defines, but several of them are unused, other are
used once. It would easier to read if these values would occure in the
place of their usage.

Also, there was an another attempt to rework bits' definition:

Internal codec on A1 SoC has ADC and this commit adds support for
capturing from it.
Also, regmap now uses caching for all platforms. Values that are written
to toacodec's register on A1 SoC can not be read back, that breaks
regmap_update_bits() functionality. Let's hope the caching will not
break anything on other platforms. Since .max_register now is explicitly
equal to 0, .reg_stride is also removed.
