If it's going to be just a single file (which I don't think it'll be in the
end), it should just be xen/common/efi.c. If there are multiple ones
(and I'd expect most of xen/arch/x86/efi/ to be re-usable), you
should just move all non-x86 code to xen/common/efi/.

Yes, I'm certainly of the opinion that each architecture should have
its own binding header, mirroring what (afaik) EFI itself does.
