ASoC: tas2770: Reinit regcache on reset
[ Upstream commit 0a0342ede303fc420f3a388e1ae82da3ae8ff6bd ]
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.
