ASoC: soc-core: remove dai_drv from snd_soc_component 

ALSA SoC has some duplicate parameter.
snd_soc_component::dai_drv is one of them.

Each DAI is keeping its driver as snd_soc_dai::driver,
and component has dai_list.
This means, we can reach to each DAI and its driver by using dai_link.
Thus, there is no need to keep DAI driver pointer on component.
Let's remove it
