In general, forward declarations are not liked. It is better to move
the code to before it is used.

Since this is a minimal fix for stable, lets allow it. But please wait
for net to be merged into net-next, and submit a cleanup patch which
does move fec_ptp_read() earlier and remove the forward declaration.
