Subject: [PATCH] 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.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202307242008.xqdjgk04-lkp@intel.com
Fixes: d24028606e76 ("ASoC: loongson: Add Loongson ASoC Sound Card Support")
