Merge series "ASoC: add soc-link" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

Current ALSA SoC is handling dai_link related operation,
but it is implmemented directly without using function/macro,
and at random place.

This v4 patch-set creates new snd_soc_link_xxx() functions
which handles dai_link related operation,
and implmement these at new soc-link.c.

v3 -> v4

	- add Reviewed-by from Ranjani and Pierre-Louis
	- fix bisection error at [2/7]

v2 -> v3

	- add missing #include <sound/soc-link.h> in soc-link.c

v1 -> v2
	- #include <sound/soc-link.h> is added on each c source file
	  instead of soc.h
	- not have extra error message after snd_soc_link_xxx(),
	  because it already indicate it via snc_link_ret()
	- snd_soc_link_compr_xxx() doesn't have rtd parameter,
	  because it can be created from cstream
