Subject: [PATCH resubmit net 1/2] net: fec: Forward-declare `fec_ptp_read()`

This function is used in `fec_ptp_enable_pps()` through
struct cyclecounter read(). Forward declarations make
it clearer, what's happening.

Fixes: 61d5e2a251fb ("fec: Fix timer capture timing in `fec_ptp_enable_pps()`")
Suggested-by: Frank Li <Frank.li@....com>
