Hi,
This version includes gating access to the hypercall page on shutdown through
a new `cpu_has_xen` global boolean. I also implemented Rogers' suggestion to
poison the hypercall page with `int3` (opcode 0xcc).
Cheers,
Alejandro

x86: Remove Xen as a hard requirement to run XTF.

x86: Poison hypercall page with `int3` rather than `ret`
