Subject[RFC PATCH] hwmon: (jc42) Add I2C_CLASS_HWMON to detection class
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.
