[PATCH] Revert "ASoC: simple-card: Fix configuration of DAI format"

Revert commit 069d037aea98 ("ASoC: simple-card: Fix configuration of
DAI format"). During further review, it turns out that the actual issue
was caused by an incorrectly formatted device-tree node describing the
soundcard.

The following is incorrect because the simple-audio-card
'bitclock-master' and 'frame-master' properties should not reference the
actual codec phandle ...

sound {
compatible = "simple-audio-card";
...
=> simple-audio-card,bitclock-master = <&codec>;
=> simple-audio-card,frame-master = <&codec>;
...

simple-audio-card,cpu {
sound-dai = <&xxx>;
};

simple-audio-card,codec {
=> sound-dai = <&codec>;
};
};

Rather, these properties should reference the phandle to the
'simple-audio-card,codec' property as shown below ...

sound {
compatible = "simple-audio-card";
...
=> simple-audio-card,bitclock-master = <&codec>;
=> simple-audio-card,frame-master = <&codec>;
...

simple-audio-card,cpu {
sound-dai = <&xxx>;
};

=> codec: simple-audio-card,codec { /* simple-card wants here */
sound-dai = <&xxx>; /* not here */
};
};
