From: Vincent Palatin <vpala...@chromium.org>
Avoid adding I2C_CLASS_HWMON and I2C_CLASS_SPD class flags to all
Samsung I2C adapters when the I2C mappings are defined in a device tree.
So the drivers doing an auto-detection by probing busses won't mess-up
sensitive I2C devices or trigger long timeouts on non-functional busses.
