Class based instantiation mechanism can cause huge delays when booting. For example: when CONFIG_SENSORS_LM75 option is enabled for or omap5-uevm board, where i2c-gpio is used for HDMI edid reading - it introduces up to 5 sec boot delay. It's not recommended to use this mechanism with embedded I2C, so disable it by leaving I2C adapter "class" field undefined (remove I2C_CLASS_HWMON and I2C_CLASS_SPD) and add a deprecation warning to allow users, relying on this mechanism, to switch to something better.
