net: dwc_eth_qos: Drop unused dm_gpio_free() on STM32

The dm_gpio_free() is never called, because for stm32, the phy_reset_gpio
pointer is never valid. This is because only tegra186 ever claims the
phy_reset_gpio, all other platforms use the PHY framework to reset the
PHY instead. Drop the dm_gpio_free() and dm_gpio_is_valid().
