[PATCH-for-5.0 0/2] hw/acpi/piix4: Restrict 'system hotplug' feature to i440fx PC machine

[Philippe Mathieu-Daudé]

This feature is not documented in the PIIX4 datasheet. It appears
to be only used on the i440fx PC machine. Add a property to the
PIIX4_PM device to restrict its use. This fixes MIPS guest crashing
QEMU when accessing ioport 0xaf00.
