Enable FIT image support and FDT loading for AST2400/AST2500

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 can be any mix of legacy or FIT images.
When using FIT images, the dtb is stored as a separate entry that
requires CONFIG_OF_LIBFDT to load it into RAM and pass it to the kernel.

U-Boot enables EFI support by default but it only builds once FIT
support is enabled.  EFI support adds ~13k to the binary and is
currently unused for any Aspeed platforms.  Explicitly disable EFI
support now that FIT support is enabled.

Tested under qemu with both legacy and FIT kernel+dtb images for
palmetto and witherspoon.
