ASoC: use internal reg_cache on uda1380
Codec reg_cache is legacy feature and very few driver only are using it. But, ALSA SoC framework needs to support it. Codec will be merged into Component in the future, so, let's remove legacy and unused feature from framework. This patch implements ALSA SoC reg_cache feature into driver, and don't use ALSA SoC framework's feature.
