    i2c: i801: Remove usage of I2C_CLASS_SPD

    Only remaining client driver supporting I2C_CLASS_SPD is jc42. This
    type of thermal sensor can be found on several DDR3/DDR4 modules.
    i2c_register_spd() instantiates also such thermal sensor i2c devices.
    Since 893fef0 ("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.
