[PATCH net v2 1/1] net: fec: fix the PTP periodic output sysfs interface

[Buday Csaba]

When the PPS channel configuration was implemented, the number of
supported periodic outputs (`n_per_out`) was left at 1.

This prohibits using channels 1..3 from the sysfs interface, since
period_store() rejects channel numbers greater than `n_per_out`.

Fix by increasing `n_per_out` to the number of channels supported
by the hardware.
