[PATCH] ASoC: samsung: Add I2C dependency for snow

[Arnd Bergmann]

Both codecs used by snow, max98090 and max98095 require the use
of I2C, so we can only select this driver if I2C is there, otherwise
we get a build error like:

codecs/max98090.c:2494:1: warning: data definition has no type or storage class [enabled by default]
 module_i2c_driver(max98090_i2c_driver);
 ^
codecs/max98095.c:2443:1: warning: data definition has no type or storage class [enabled by default]
 module_i2c_driver(max98095_i2c_driver);
 ^

This adds one more I2C dependency to the hundreds we already
have.
