This misses kexec_file_load.

Right, thanks, I will fix that in the next version.

Also, is a new hook really needed?  E.g. the SEV-ES check be shoved
into machine_kexec_prepare().  The downside is that we'd do a fair
amount of work before detecting failure, but that doesn't seem hugely
problematic.

That could work, but I think its more user-friendly to just claim that
the syscalls are not supported at all.
