[PATCH v1] ALSA: hda: tas2563: mark const variables as __maybe_unused

From: Shenghao Ding

From: Baojun Xu <baojun.xu@xxxxxx>

An earlier patch changed the DECLARE_TLV_DB_SCALE declaration, but
now there are additional static const variables that cause
the same build warnings:

In file included from sound/pci/hda/tas2781_hda_i2c.c:23:
include/sound/tas2563-tlv.h:21:28: error: 'tas2563_dvc_table' defined but not used [-Werror=unused-const-variable=]
21 | static const unsigned char tas2563_dvc_table[][4] = {
| ^~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~

Mark it as unused as well.
