acpi_piix4: Disallow write to up/down PCI hotplug registers The write side of these registers is never used and actually can't be used as defined because any read/modify/write sequence from the guest potentially races with qemu. Drop the write support and define these as read-only registers. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
