The LED GPIO pins (GPIO3/4/5, mapped to LED2/LED1/LED0) are only ever
configured as outputs once, in .probe(). But .config_init() restarts
the MD32 MCU via en8811h_restart_mcu() on every call after the first
(priv->mcu_needs_restart), and that restart resets buckpbus-mapped MCU
state, including EN8811H_GPIO_OUTPUT. As a result the LED GPIOs fall
back to inputs after the first event that re-triggers .config_init()
(link renegotiation, ifdown/ifup, resume), and the PHY's LEDs stop
reflecting link/activity state even though they worked right after
probe.
Move the GPIO-as-output configuration from .probe() to the end of
.config_init(), so it is reapplied every time the MCU may have been
restarted.
