vc/amd/fsp/picasso: Add AMD code to support psp_verstage
Add the AMD supplied code (modified to work with GCC) to the vendorcode
directory. Verstage will be running on the PSP as a userspace
application under the bootloader, which is what bl_uapp signifies.
AMD is still working on documentation for the entire PSP userspace
application interface.
