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.
