Subject: [PATCH] qemu: Drop OVMF whitelist

As discussed on the upstream list, it's better not to make this
kind of predictions in libvirt. It may happen that qemu learns
how to enable OVMF on other architectures too and we shouldn't
try to chase that.

(cherry picked from commit 36148120c1c1e6ad7f4eb6f0995eb7b18ba95922)
