In 2011, commit 774466add7c810fd7e4c8bcf41995b6799608880 changed the detection class of these chips to I2C_CLASS_SPD based on this premise: "makes more sense because these chips always live on memory modules"
Today these chips have applications beyond memory modules. Add I2C_CLASS_HWMON as an additional detection class to allow detection by hwmon class i2c adapters. Alternative is to replace the SPD w HWMON class, but that carries risk for existing usage.
