Subject: [PATCH v3 11/20] ASoC: tas2764: Raise regmap range maximum

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

TAS2764 has a number of undocumented registers between
page 0xf0 and 0xff. These are used to apply in-silicon
quirks and workarounds at runtime.

Raise the regmap max register to 0xffff to cover any
quirks registers.
