net: stmmac: drop the reset GPIO from struct stmmac_mdio_bus_data
No platform uses the "reset_gpio" field from stmmac_mdio_bus_data
anymore. Drop it so we don't get any new consumers either.
Plain GPIO numbers are being deprecated in favor of GPIO descriptors. If
needed any new non-OF platform can add a GPIO descriptor lookup table.
devm_gpiod_get_optional() will find the GPIO in that case.
