at table to need
to pass that option to qemu. But if gfx_passthru_kind = "igd" we always
force to pass that.
And "-gfx_passthru" is just introduced to work for qemu-xen-traditional
so we should get this away from libxl__build_device_model_args_new() in
the case of qemu u
and build_info.u.gfx_passthru_kind to IGD
And note actually that option "-gfx_passthru" is just introduced to
work for qemu-xen-traditional so we should get this away from
libxl__build_device_model_args_new() in the case of qemu upstream.
