Class based instantiation mechanism can cause huge delays when booting.
For example: when CONFIG_SENSORS_LM75 option is enabled for omap4-sdp board -
it introduces 5-6 ms 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).
