Adds commands so that when a secure device is in use and the SPL is
built to load a FIT image (with combined U-Boot binary and various
DTBs), these components that get fed into the FIT are all processed to
be signed/encrypted/etc. as per the operations performed by the
secure-binary-image.sh script of the TI SECDEV package. Furthermore,
perform minor comments cleanup to make better use of the available
space.
