mpc85xx: Add PTP node for TL-WD4900 in device tree
PTP requires at least one timer to be 1PPS so describe it. For testing, load kernel module gianfar_ptp and use ptp4l from linuxptp. Copied from FSL P1010RDB reference design. Signed-off-by: Wojciech Dubowik <Wojciech.Dubowik@neratec.com> SVN-Revision: 48275
