[PATCH] ASoC: max98988: add I2C dependency

[Arnd Bergmann]

max98988 only builds with I2C support enabled, otherwise we get a build error:

sound/soc/codecs/max98088.c:1789:1: error: data definition has no type or storage class [-Werror]
 module_i2c_driver(max98088_i2c_driver);
 ^~~~~~~~~~~~~~~~~
sound/soc/codecs/max98088.c:1789:1: error: type defaults to 'int' in declaration of 'module_i2c_driver' [-Werror=implicit-int]
sound/soc/codecs/max98088.c:1789:1: error: parameter names (without types) in function declaration [-Werror]
sound/soc/codecs/max98088.c:1780:26: error: 'max98088_i2c_driver' defined but not used [-Werror=unused-variable]
