Moritz Fischer 71bd106d25 net: fixed-phy: Add fixed_phy_register_with_gpiod() API
Add fixed_phy_register_with_gpiod() API. It lets users create a
fixed_phy instance that uses a GPIO descriptor which was obtained
externally e.g. through platform data.
This enables platform devices (non-DT based) to use GPIOs for link
status.
