Add property to select the preferred hardware timestamp layer.
The choice of using devicetree binding has been made as the PTP precision
and quality depends of external things, like adjustable clock, or the lack
of a temperature compensated crystal or specific features. Even if the
preferred timestamp is a configuration it is hardly related to the design
of the board.
