[PATCH] ASoC: loongson: mark OF related data as maybe unused

[YingKun Meng]

The ASoC Sound Card driver can be compile tested with !CONFIG_OF
making 'loongson_asoc_dt_ids' unused:

sound/soc/loongson/loongson_card.c:200:34: warning: unused variable 'loongson_asoc_dt_ids' [-Wunused-const-variable]

Here we solve it in the same way as [1].
