[PATCH] media: i2c: TDA1997x: add CONFIG_SND dependency

[Arnd Bergmann]

Without CONFIG_SND, we get a link error:

ERROR: "snd_soc_register_codec" [drivers/media/i2c/tda1997x.ko] undefined!
ERROR: "snd_soc_unregister_codec" [drivers/media/i2c/tda1997x.ko] undefined!
ERROR: "snd_pcm_hw_constraint_minmax" [drivers/media/i2c/tda1997x.ko] undefined!

This adds the same Kconfig dependency that we have in other
media drivers, using 'select SND_PCM' to ensure that we have
can call snd_pcm_hw_constraint_minmax, while depending on
CONFIG_SND_SOC for registering the codec.
