In case "gpio-ranges" property is not present in device tree, use default value for gpio_count and gpio_range. This fixes an issue on stm32 F7 and H7 boards where "pinmux status -a" command didn't return any pin status due to the fact that both stm32 F7 and H7 board DT doesn't use the gpio-ranges property.
