[-next] ASoC: rt5682: Fix build error without CONFIG_I2C

Commit Message

If I2C is n but SoundWire is m, building fails:

sound/soc/codecs/rt5682.c:3716:1: warning: data definition has no type or storage class
 module_i2c_driver(rt5682_i2c_driver);
 ^~~~~~~~~~~~~~~~~
sound/soc/codecs/rt5682.c:3716:1: error: type defaults to ‘int’ in declaration of ‘module_i2c_driver’ [-Werror=implicit-int]
sound/soc/codecs/rt5682.c:3716:1: warning: parameter names (without types) in function declaration

Guard this use #ifdef CONFIG_I2C.

I imagine that the device is going to need power even when use with
slimbus, even if the regulator support isn't wired up at the minute.
For things like this __maybey_unused annotations tend to be better, 
this stops warnings about things not being used but doesn't need ifdefs
or big code moves.
