If we are in a multi-master scenario, we need to block runtime PM so the arbitration circuit stays awake.
So, we define a new binding and adapt the i2c-rcar driver to have an example implementation. This series is RFC because I want to do some more regression testing. The actual functionality works fine here on my Lager board.
