Kuninori Morimoto 7ba236ce58 ASoC: add Component level set_bias_level 
In current ALSA SoC, Codec only has set_bias_level feature.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

Codec driver has .idle_bias_off for dapm bias. But Component
driver doesn't have it, and dapm->idle_bias_off is set as "true".
To keep compatibility, this patch adds "idle_bias_on" instead of
".idle_bias_off" on Component driver.
dapm->idle_bias_off will be set by inverted idle_bias_on.

When we replace Codec to Component, the driver which has
".idle_bias_off = true" is just remove it,
and the driver which doesn't have it will have new
".idle_bias_on = true".
