SECURE BOOT: Add fall back option
Add fall back option, to boot from NOR/QSPI/SD for LS1043, LS1046, LS1021 in case of distro boot failure. For LS1046, add kernel validation in case of secure boot in sd_bootcmd and qspi_bootcmd. For LS1043 and LS1021, add kernel validation in case of secure boot in sd_bootcmd, qspi_bootcmdand nor_bootcmd.
