ASoC: loongson: drop of_match_ptr for OF device id

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]

As krzysztof advice, we drop of_match_ptr so the device id
can also be used on ACPI.
