spl: Add full fitImage support
Add support for loading U-Boot and optionally FDT from a fitImage
in SPL by using the full fitImage support from U-Boot. While we do
have limited SPL loading support in SPL with a small footprint, it
is missing a lot of important features, like checking signatures.
This support has all the fitImage features, while the footprint is
obviously larger.
