ASoC: rt700: don't set dapm->bias_level

snd_soc_component_set_bias_level() (A) which will call .set_bias_level()
callback (B) will be called from snd_soc_dapm_force_bias_level() (C) only,
and it sets dapm->bias_level (D) inside. No need to set it by each driver.
Remove it.

(A)	int snd_soc_component_set_bias_level(...)
	{
		...
		if (component->driver->set_bias_level)
(B)			ret = component->driver->set_bias_level(...);
		...
	}

(C)	int snd_soc_dapm_force_bias_level(...)
	{
		...
		if (dapm->component)
(A)			ret = snd_soc_component_set_bias_level(...);

		if (ret == 0)
(D)			dapm->bias_level = level;
		...
	}
