[PATCH 2/3] ASoC: rt5682: fix compilation issues without I2C

[Pierre-Louis Bossart]

Exclude all I2C-related code from compilation to avoid compilation
errors and defined but not used warnings.

sound/soc/codecs/rt5682.c:3688:26: warning: 'rt5682_i2c_driver'
defined but not used [-Wunused-variable]
    static struct i2c_driver rt5682_i2c_driver = {
                             ^~~~~~~~~~~~~~~~~
