led-red and button dedicated to fastboot share the same gpio GPIOA13. led-blue and button dedicated to stm32prog share the same gpio GPIOA14. Led driver is probed early so the corresponding gpio is taken and configured in output which forbid fastboot and stm32prog button usage.
To avoid this, remove the "default-state" property from led-red and led-blue led's node.
This will avoid to trigger the led driver probe() to configure the led default state during startup.
