net: fec: prevent undesired de-assertion of phy-reset on request
When gpio_request_by_name allocates a gpio output it by default will
de-assert the gpio which for phy-reset will take the PHY out of reset.
As this occurs before fec_gpio_reset is called to assert the reset
line it can cause undesired affects if reset timings are not properly
met.
Configure the gpio with GPIOD_IS_OUT_ACTIVE so that reset is kept active
(reset asserted) to avoid this.
