Hi Mark
Cc Bard, Pierre-Louis, Jerome, DT-ML

This is v6 patch-set.

Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using
ch_map idea. This patch-set expands it that all connection uses this idea,
and no longer N < M limit [1][2].

v5 have changed basic idea, and Intel might got some effect, but was Tested-by
Pierre-Louis.  Jerome's environment might got some effect, but it is less than
Intel and similar environment was already tested by Audio-Graph-Card2 and its
test dtsi. Thus, I added their Tested-by on v5 patch.

v5 -> v6
	- tidyup some warnings
	- rename "ch-map-idx" -> "channel-map-index"
	- Update "channel-map-index" description
	- add Tested-by from Pierre-Louis / Jerome

v4 -> v5
	- use cpu/codec index on ch_maps
	- separate card2 sample DT patch into prepare and new feature
	- ch-maps -> ch-map-idx on DT

v3 -> v4
	- add Jerome on To
	- add "description" on "ch-maps"

v2 -> v3
	- tidyup comment
	- use more clear connection image on DT
	- "ch_maps" -> "ch-maps" on DT
	- Add DT maintainer on "To:" for all patches

v1 -> v2
	- makes CPU/Codec connection relation clear on comment/sample
	- fixup type "connction" -> "connection"
	- makes error message clear
