The conversion to gpio descriptors accidentally removed the short return
if there is no 'phy-reset-gpios' property, leading to the error

fec 30be0000.ethernet: error -ENOENT: failed to get phy-reset-gpios

This is especially the case when the PHY reset GPIO is specified in
the PHY node itself.

Fixes: 468ba54bd616 ("fec: convert to gpio descriptor")

Fixed around the same time by commit d7b5e5dd669436 right?

Yes, this does the trick as well. Thanks
