When the part is reset in component_probe, do not forget to reinit the
regcache, otherwise the cache can get out of sync with the part's
actual state. This fix is similar to commit 0a0342ede303
("ASoC: tas2770: Reinit regcache on reset") which concerned the
tas2770 driver.

Fixes: 827ed8a0fa50 ("ASoC: tas2764: Add the driver for the TAS2764")

As previously and repeatedly mentioned please put fixes at the start of
patch serieses so they don't end up with spurious dependencies on other
non-fix patches.
