ASoC: tas2781: mark dvc_tlv with __maybe_unused

Browse Source 
[ Upstream commit 831ec5e353 ]

Since we put dvc_tlv static variable to a header file it's copied to
each module that includes the header. But not all of them are actually
used it.

Fix this W=1 build warning:

include/sound/tas2781-tlv.h:18:35: warning: 'dvc_tlv' defined but not
used [-Wunused-const-variable=]
