In coreboot, we mark GPU prefmem above 4GB, because NVIDIA wants a lot
(16GB region on the 30 series), otherwise coreboot will obviously fail
to allocate the resources.
In EDK2, we then end up hitting this assert:
InitRootBridge: populated root bus 0, with room for 36 subordinate bus(es)
RootBridge: PciRoot(0x0)
Support/Attr: 7001F / 7001F
DmaAbove4G: No
NoExtConfSpace: No
AllocAttr: 0 ()
Bus: 0 - 24 Translation=0
Io: 1000 - EFFF Translation=0
Mem: 80400000 - 1001FFFFFF Translation=0
MemAbove4G: FFFFFFFFFFFFFFFF - 0 Translation=0
PMem: FFFFFFFFFFFFFFFF - 0 Translation=0
PMemAbove4G: FFFFFFFFFFFFFFFF - 0 Translation=0
ASSERT [PciHostBridgeDxe] .../edk2/MdeModulePkg/Bus/Pci/PciHostBridgeDxe/PciRootBridgeIo.c(120): Bridge->Mem.Limit < 0x0000000100000000ULL
So, bring back Pci*NoEnumerationDxe from the deleted DuetPkg, which
doesn't check anything and let's us boot.
