[RFC][PATCH 2/2 v2] ASoC: simple-card: add Device Tree support

Hi Mark, Stephen

I would like to ask you before creating v3 patch.
I got some opinions from you.
 - cpu/codec style (above)
 - "controller" naming
 - it is using "name" property (it is must item for matching)

Then, what do you think about this style ?

fai_ak4642 {
        compatible = "simple-audio";

        simple-audio,card-name = "FSI2A-AK4648";

        /* platform */
        simple-audio,platform {
             compatible = "ak4642-hifi";  /* platform name (if needed) */
             simple-audio,dev = <&sh_fsi2>;

             /* format and inversion are here */
             simple-audio,format = "left_j";
             simple-audio,bitclock-inversion;
        }

        /* codec and cpu are same style */

        /* codec */
        simple-audio,codec {
             compatible = "ak4642-hifi";  /* codec dai name (this is must item on ASoC) */
             simple-audio,dev = <&ak4648>;
             simple-audio,bitclock-master;
 
             /* clock gating is here */
            simple-audio,clock-gating = "continuous";
        }

        /* cpu */
        simple-audio,cpu {
             compatible = "fsia-dai"; /* cpu dai name (if needed) */
             simple-audio,dev = <&sh_fsi2>;
             simple-audio,system-clock-frequency = <11289600>;
        }
}
