hw/xen: Set emu_mask for igd_opregion register
In igd passthrough environment, guest could only access opregion at the first bootup time. Once guest shutdown, later guest couldn't access opregion anymore. This is because qemu set emulated guest opregion base address to host register. Later guest get a wrong host opregion base address, and couldn't access it anymore. This patch set emu_mask for igd_opregion register, so guest won't set guest opregion base address to host.
