The FWU Multi Bank Update feature allows the platform to boot the firmware images from one of the partitions(banks). The first stage bootloader(fsbl) passes the value of the boot index, i.e. the bank from which the firmware images were booted from to U-Boot. On the STM32MP157C-DK2 board, this value is passed through one of the SoC's backup register. Add a function to read the boot index value from the backup register.
