Set the PTP shaper parameters during the ptp_init(). For different
speeds, there are different parameters.

When the port's speed changes and PTP shaper is enabled, the firmware
changes the ETS shaper values according to the PTP shaper parameters for
this new speed.

The PTP shaper parameters array is left empty for now, will be filled in
a follow-up patch.
