The Intel GPU uses a two pages NVS region called OpRegion. In order to get full support for the driver in the guest we need to map this region. This patch reserves 2 pages on the top of the memory in the reserved area and mark this region as NVS in the e820. Then we write the address to the config space (offset 0xfc) so the device model can map the OpRegion at this address in the guest.
