I think commit `ACPI: Rebuild ACPI tables on every read` can be dropped, IIRC
this was necessary when SVSM consumed MADT from fw_cfg.

In `qdev: Add plane property`, in function `device_initfn`, dev->plane
should be set to `qdev_default_plane()`
see https://github.com/coconut-svsm/qemu/pull/31/changes/8fa10020cb97ced3151f67b842ecba57ef76765e
