[PATCH] ASoC: tas2781: fix unused-const-variable warning

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

When both CONFIG_OF and CONFIG_ACPI are disabled, the ID table is not
referenced any more:

sound/soc/codecs/tas2781-i2c.c:102:35: error: 'tasdevice_id' defined but not used [-Werror=unused-const-variable=]
  102 | static const struct i2c_device_id tasdevice_id[] = {
      |                                   ^~~~~~~~~~~~

Remove the #ifdef checks and just include the ID tables unconditionally
to get a clean build in all configurations. The code already uses
IS_ENABLED() checks for both to benefit from dead code elimination
and the ID tables are small enough that they can just be included
all the time.

Fixes: 9a52d1b7cb4a ("ASoC: tas2781: Explicit association of Device, Device Name, and Device ID")
