[PATCH] ALSA: core: fix unit test dependencies

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The Kunit tests fail to link when PCM support is disabled:

aarch64-linux-ld: sound/core/sound_kunit.o: in function `test_pcm_format_name':
sound_kunit.c:(.text+0x4c): undefined reference to `snd_pcm_format_name'
aarch64-linux-ld: sound_kunit.c:(.text+0x12c): undefined reference to `snd_pcm_format_name'
aarch64-linux-ld: sound/core/sound_kunit.o: in function `_test_fill_silence':
sound_kunit.c:(.text+0x284): undefined reference to `snd_pcm_format_set_silence'
aarch64-linux-ld: sound/core/sound_kunit.o: in function `test_format_signed':
sound_kunit.c:(.text+0x400): undefined reference to `snd_pcm_format_signed'
aarch64-linux-ld: sound_kunit.c:(.text+0x470): undefined reference to `snd_pcm_format_unsigned'
aarch64-linux-ld: sound/core/sound_kunit.o: in function `test_format_width':
sound_kunit.c:(.text+0x64c): undefined reference to `snd_pcm_format_width'
aarch64-linux-ld: sound_kunit.c:(.text+0x71c): undefined reference to `snd_pcm_format_width'

Add the appropriate dependencies.
