I got another build error from SND_SOC_SMARTQ selecting
SND_SOC_WM8750 without ensuring that I2C is enabled,
in this example, i2c is a loadable module:

sound/built-in.o: In function `wm8750_i2c_probe':
:(.text+0x3e6c0): undefined reference to `devm_regmap_init_i2c'
sound/built-in.o: In function `wm8750_exit':
:(.exit.text+0x3f4): undefined reference to `i2c_del_driver'
sound/built-in.o: In function `wm8750_modinit':
:(.init.text+0x13d0): undefined reference to `i2c_register_driver'

This changes the samsund ASoC Kconfig to have explicit
I2C dependencies for each driver that uses an i2c bus and
SPI dependencies for the ones using those.
