    Pull i2c updates from Wolfram Sang:
     "Quite some driver updates:
       - piix4 can now handle multiplexed adapters
       - brcmstb, xlr, eg20t, designware drivers support more SoCs
       - emev2 gained i2c slave support
       - img-scb and rcar got bigger refactoring to remove issues
       - lots of common driver updates
    
      i2c core changes:
       - new quirk flag when an adapter does not support clock stretching,
         so clients can be configured to avoid that if possible
       - added a helper function to retrieve timing parameters from firmware
         (with rcar being the first user)
       - "multi-master" DT binding added so drivers can adapt to this
         setting (like disabling PM to keep arbitration working)
       - RuntimePM for the logical adapter device is now always enabled by
         the core to ensure propagation from childs to the parent (the HW
         device)
       - new macro builtin_i2c_driver to reduce boilerplate"
