Modify the SPL build procedure for AM57xx and DRA7xx high-security (HS) device variants to create a secure u-boot_HS.img FIT blob that contains U-Boot and DTB artifacts signed with a TI-specific process based on the CONFIG_TI_SECURE_DEVICE config option and the externally-provided image signing tool.
Also populate the corresponding FIT image post processing call to be performed during SPL runtime.
