    drm: Implement and use the Linux i2c API
    
    * This is mainly to the benefit of the drm/i915 driver
    
    * Sync key portions of code with Linux 4.4
    
    * Key drm functions using the DragonFly-specific iic(4) API
      have been copied and renamed with an _iic suffix
    
    * The drm/radeon driver no longer being actively developed, the
      intent is to keep it functional with a frozen API
    
    Thanks to Johannes Hofmann for figuring out we could live with
    a dummy default bit_xfer() implementation
