ASoC: soc-compress: use function to clear symmetric params

ASoC: soc-compress: use function to clear symmetric params

Current soc-compress.c clears symmetric_rate, but it clears rate only,
not clear other symmetric_channels/sample_bits.

	static int soc_compr_clean(...)
	{
		...
		if (!snd_soc_dai_active(cpu_dai))
=>			cpu_dai->symmetric_rate = 0;

		if (!snd_soc_dai_active(codec_dai))
=>			codec_dai->symmetric_rate = 0;
		...
	};

This feature was added when v3.7 kernel [1], and there was only
symmetric_rate, no symmetric_channels/sample_bits in that timing.

symmetric_channels/sample_bits were added in v3.14 [2],
but I guess it didn't notice that soc-compress.c is updating symmetric_xxx.

We are clearing symmetry_xxx by soc_pcm_set_dai_params(), but is soc-pcm.c
local function. Makes it global function and clear symmetry_xxx by it.
