Merge series "ASoC: simple-card-utils: prepare for multi support" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

I want to add new audio-graph-card2 driver which can support
not only DPCM, but also Multi-CPU/Codec, and Codec2Codec.
And it is also supporting audio-graph-card2 base custom driver.

But before supporting such driver, we need to cleanup existing
simple-card / audio-graph, because these and new driver are
sharing code.

This patch-set are for Multi-CPU/Codec support,
and some cleanups.

Kuninori Morimoto (14):
  ASoC: simple-card-utils: enable flexible CPU/Codec/Platform
  ASoC: simple-card-utils: share dummy DAI and reduce memory
  ASoC: simple-card-utils: setup dai_props cpu_dai/codec_dai at initial timing
  ASoC: simple-card-utils: remove li->dais/li->conf
  ASoC: simple-card-utils: use for_each_prop_xxx()
  ASoC: simple-card-utils: remove asoc_simple_parse_xxx()
  ASoC: simple-card-utils: care multi DAI at asoc_simple_clean_reference()
  ASoC: simple-card-utils: indicate dai_fmt if exist
  ASoC: simple-card-utils: indicate missing CPU/Codec numbers for debug
  ASoC: simple-card-utils: add simple_props_to_xxx() macro
  ASoC: simple-card-utils: multi support at asoc_simple_canonicalize_cpu/platform()
  ASoC: simple-card-utils: tidyup debug info for clock
  ASoC: simple-card-utils: tidyup dev_dbg() to use 1 line
  ASoC: simple-card-utils: tidyup asoc_simple_parse_convert()
