Fix kconfig warning that is caused by DVB_TS2020:

warning: (DVB_TS2020 && SND_SOC_ADAU1761_I2C && SND_SOC_ADAU1781_I2C && SND_SOC_ADAU1977_I2C && SND_SOC_RT5677 && EXTCON_MAX14577 && EXTCON_MAX77693 && EXTCON_MAX77843) selects REGMAP_I2C which has unmet direct dependencies (I2C)

This fixes many subsequent build errors.
