Hi Mark

Now, ALSA SoC calls 2 type of suspend/resume

	suspend/resume for Component
	suspend/resume for DAI

When ALSA SoC calls suspend/resume, its orders are

	1) Suspend/Resume all CPU DAI if bus-control was 0
	2) Suspend/Resume all Component
	3) Suspend/Resume all CPU DAI if bus-control was 1

Historically 2)'s "Component" was "Codec", before.
In total,
CPU   has 3 chance to suspend/resume(= 1/2/3), but
Codec has 1 chance to suspend/resume(= 2).

And now, no driver which is supporting suspend/resume has bus-control.
This means 3) is never used.

Almost all drivers which is using DAI suspend/resume can simply switch
to Component suspend/resume.
Few drivers want to use/keep DAI, but, we can call all DAI from Component
by using this if needed

	for_each_component_dais()

These patches switches all DAI's suspend/resume to Component one,
and removes it.
