[PATCH -next] ASoC: amd: acp-da7219-max98357a: Fix -Wunused-variable warning

[YueHaibing <yuehaibing@huawei.com>]

While ACPI is not set, make W=1 warns:

sound/soc/amd/acp-da7219-max98357a.c:684:28: warning: ‘cz_rt5682_card’ defined but not used [-Wunused-variable]
 static struct snd_soc_card cz_rt5682_card = {
                            ^~~~~~~~~~~~~~
sound/soc/amd/acp-da7219-max98357a.c:671:28: warning: ‘cz_card’ defined but not used [-Wunused-variable]
 static struct snd_soc_card cz_card = {

Use #ifdef block to guard this.
