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.
