Add the board-specific properties of the DFLL for the Jetson TK1 board.
On this board, the DFLL will take control of the sd0 regulator on the
on-board AS3722 PMIC.

v2 changes:
    - same changes that were done to the binding in patch 3
        * dropped most of the I2C properties, as they are now queried from
          the regulator framework
        * s/vdd_cpu-supply/vdd-cpu-supply/ to better match what other Tegra
          bindings do
