    openrgb: Deduplicate piix4 setup for HUDSON2/KERNCZ SMBUS

    In the original OpenRGB patches, the initialization code for CZ
    secondary SMBus controllers was copied.  Later, an upstream commit
    landed in 5.7 stable that combined the initialization code for both
    primary/secondary smbus channels.

    Combine the initialization code ahead of time so upstream merges
    correctly with OpenRGB.

    Fixes: #176
