When assign EHCI device to the virtual machine, after initializing EHCI in seabios,it will continuously send dma cycles. Flatview_simplify() will merge a very large range.The IOVA mappings of the EHCI device will be innocently unmapped between the delete and add phases of the VFIO MemoryListener. At this time,the IOMMU will block the DMA cycle. We want to remove flatview_simplify() is to prevent EHCI device IOVA mappings from being unmapped.
