FSP initializes the VT-d feature on Broadwell-DE and assigns an address space to the MMIO range. coreboot's resource allocator needs to be aware of this fixed resource as otherwise the address can be assigned to a different PCI device. In this case addresses are overlapped and the VT-d range is not accessible any more. To deal with it the right way add a fixed MMIO resource to the resources list if VT-d BAR is enabled. TEST=Booted into Linux and checked coreboot log for resource assignment.
