net: fec: Do a sanity check on the gpio number
Check whether the phy-reset GPIO is valid, prior to requesting it.
In the case a board does not provide a phy-reset GPIO, just returns immediately.
With such gpio validation in place, it is also safe to change from pr_debug to
dev_err in the case the gpio request fails.
