net: fec: restore handling of PHY reset line as optional

Conversion of the driver to gpiod API done in 468ba54bd616 ("fec:
convert to gpio descriptor") incorrectly made reset line mandatory and
resulted in aborting driver probe in cases where reset line was not
specified (note: this way of specifying PHY reset line is actually
deprecated).

Switch to using devm_gpiod_get_optional() and skip manipulating reset
line if it can not be located.
