This type of thermal sensor can be found on several DDR3/DDR4 modules. i2c_register_spd() instantiates also such thermal sensor i2c devices. Since 71b494e043d2 ("i2c: i801: Call i2c_register_spd for muxed child segments") i2c_register_spd() is called also for the remaining use case, systems with muxed SMBUS segments for SPD EEPROMs. Therefore I2C_CLASS_SPD class-based instantiation isn't needed any longer in this driver, so remove it.
