The GPIOD API handles GPIO active assertion levels as defined by the
DT binding. So the phy-reset-active-high and/or phy-reset-active-low
property is not needed when using the GPIOD API - just define
GPIO_ACTIVE_LOW or GPIO_ACTIVE_HIGH as required for the board and the
GPIOD API will handle active assert/deassert level as needed.
