[PATCH 07/27] ASoC: tas2764: Reinit cache on part reset

[James Calligeros <jcalligeros99@gmail.com>]

From: Martin Povišer <povik+lin@cutebit.org>

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 which
concerned the tas2770 driver.)

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