Otherwise, dai bit clocks can be be gated

Why are these selectable in the machine driver?
I have tested and found that sai<->aif1 can support "i2s" "left_j" "dsp_a" "dsp_b" format, and can support cpu dai master and slave mode. But I haven't tested voice dai and bt dai because of hardware limitation. I just using sai<->aif2 to test aif2.
So I want to configure the dai format from device tree. And there is a help function snd_soc_of_parse_daifmt for me to do this, so I add these selectable to the machine driver.
model = "wm8960-audio";
Cut'n'paste error here.
it should be "wm8958-audio", i will modify it.
