ASoC: tas2770: Reinit regcache on reset 



On probe of the ASoC component, the device is reset but the regcache is
retained. This means the regcache gets out of sync if the codec is
rebound to a sound card for a second time. Fix it by reinitializing the
regcache to defaults after the device is reset.
