Kuninori Morimoto 8cc0372240 ASoC: rsnd: add rsnd_soc_hw_rule/constraint()
Current Renesas sound driver is assuming that all Sampling rate and
channles are possible to use, but these are depends on inputed clock
and SSI connection situation.
For example, if it is using 1 SSI, enabled TDM mode and has 12288000
input clock, 2ch output can support until 192000Hz, but 6ch output can
support until 64000Hz, 8ch can support 48000Hz.
To control these situation correctly, it needs to support
hw_constraints / refine feature.

To support such feature, this patch adds new
rsnd_soc_hw_rule/constraint() which adds hw rule of Channel and
Sampling Rate.
