reboot-mode: read the boot mode from GPIOs status
A use case for controlling the boot mode is when the user wants to control the device boot by pushing a button without needing to go in user-space. Add a new backed for reboot mode where GPIOs are used to control the reboot-mode. The driver is able to scan a predefined list of GPIOs and return the magic value. Having the modes associated with the magic value generated based on the GPIO values, allows the reboot mode uclass to select the proper mode.
