The IGVM parameter handler is implemented for the i386 machine
target and stubbed for all others.

Hmm, why?  I can't see anything i386-specific in that code, it should
work just fine everywhere.  For example on aarch64 (which is not yet
supported by qemu but already in the igvm specification).

Right, good point. I think this function can be moved to `backends/igvm.c`
directly, so we'll have aarch64 DT support for free.
