spapr_iommu: Disable in-kernel IOMMU tables for >4GB windows
The existing KVM_CREATE_SPAPR_TCE ioctl only support 4G windows max as the window size parameter to the kernel ioctl() is 32-bit so there's no way of expressing a TCE window > 4GB. We are going to add huge DMA windows support so this will create small window and unexpectedly fail later. This disables KVM_CREATE_SPAPR_TCE for windows bigger that 4GB.
