When running as an EFI application, U-Boot must request memory from EFI, and provide access to the boot services U-Boot needs.
Add library code to perform these tasks. This includes efi_main() which is the entry point from EFI. U-Boot is built as a shared library.

Can we also remove those duplicated defines in arch/x86/include/asm/fsp/fsp_types.h so that FSP codes can use the one in efi.h?
But these have an FSP prefix, right? If you are sure about this, I'll do it as a separate clean-up patch.
According to FSP spec, FSP is using EFI status codes, so they are compatible. We can do it as a separate clean-up patch later.
