Adding FASTBOOT support for stm32mp13 shows issues when entering in fastboot mode using a dedicated key. On several STM32MP boards, same gpio is shared between key and led. Restore the fastboot/stm32prog activation using a dedicated key. Restore the led-blue which indicates U-Boot entering / exit. Make usage of BUTTON-UCLASS for key management on STM32MP1.
