We have a lot of EFI definitions, both inside efi.h and outside, including some things that are only payload-specific.
Let's tidy that up and clearly split generic functionality and definitions from the payload-specific pats. While at it, we also remove the redundant efi- prefix in headers and retire the efi.h header to avoid non-portable parts making it into there.
