Alex Williamson ba737541ed 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.
