ptp: Add a driver for InES time stamping IP core.
The InES at the ZHAW offers a PTP time stamping IP core. The FPGA
logic recognizes and time stamps PTP frames on the MII bus. This
patch adds a driver for the core along with a device tree binding to
allow hooking the driver to MII buses.

In order for this to work, your MAC driver must also
implement the skb_tx_timestamp() function.
