ASoC: samsung: tobermory: don't set dapm->bias_level directly

snd_soc_dapm_set_bias_level() (A) will set dapm->bias_level (a) inside.
No need to set it by each callback function. Remove it.

(A)	static int snd_soc_dapm_set_bias_level(...)
	{
		...
		/* success */
		if (ret == 0)
(a)			snd_soc_dapm_init_bias_level(dapm, level);
		...
	}
