[PATCH u-boot] Enable FIT image support and FDT loading for AST2400/AST2500

[Rick Altherr]

FIT is the modern u-boot native image format for kernels, device trees,
and ramdisks.  Enabling FIT only compiles in support for the image
format.  For these devices, the kernel+dtb and ramdisk are loaded from
separate locations in flash and be any mix of legacy or FIT images.
When using FIT images, the dtb is stored as a separate entry that
requires additional support to load it into RAM and pass it to the
kernel.
