arm: am4x: add U-Boot FIT signing and SPL image post-processing
Modify the SPL build procedure for AM437x high-security (HS) device
variants to create a secure u-boot_HS.img FIT blob that contains U-Boot
and DTB artifacts signed (and optionally encrypted) 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.
