Subject: [PATCH] ASoC: mediatek: add i2c dependency

The newly added mediatek drivers for mt8173 select codes that depend
on I2C, which cuases a build failure if I2C is disabled:

warning: (SND_SOC_ADAU1761_I2C && SND_SOC_ADAU1781_I2C && SND_SOC_ADAU1977_I2C && SND_SOC_RT5677 && EXTCON_MAX14577 && EXTCON_MAX77693 && EXTCON_MAX77843 && BMC150_ACCEL_I2C && BMG160_I2C) selects REGMAP_I2C which has unmet direct dependencies (I2C)
codecs/rt5645.c:3854:1: warning: data definition has no type or storage class
codecs/rt5645.c:3854:1: error: type defaults to 'int' in declaration of 'module_i2c_driver' [-Werror=implicit-int]
codecs/rt5677.c:5270:1: warning: data definition has no type or storage class
77_i2c_driver);

codecs/rt5677.c:5270:1: error: type defaults to 'int' in declaration of 'module_i2c_driver' [-Werror=implicit-int]

This adds an explicit dependency.
