ASoC: update auto format selection method

Current DAI supports auto format selection. It allow to have array like
below.

(X)	static u64 xxx_auto_formats[] = {
(A)		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J,

		/* Second Priority */
(B)		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,
	};

It try to find available format from I2S/LEFT_J first (A).
Then, try to find from I2S/LEFT_J/DSP_A/DSP_B if couldn't find (A)+(B).
(OR:ed)

In this method, it can't handle if there is format combination.
For example, some driver has pattern.

Pattern1
	I2S/RIFHT_J/LEFT_J (FORMAT) and NB_NF/IB_IF/IB_NF/NB_IF (INV)_
Pattern2
	DSP_A/DSP_B        (FORMAT) and NB_NF/      IB_NF

Because it will try to OR Pattern1 and Pattern2, un-supported
pattern might be selected.

This patch update method not to use OR, and assumes full format array.
Above sample (X) need to be

	static u64 xxx_auto_formats[] = {
		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J,

		/* Second Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,
	};

Note: It doesn't support Multi CPU/Codec for now
