    CHANGELOG.md: Mention PCI passthrough for HVM domUs
    
    PCI passthrough is already supported for HVM domUs when dom0 is PVH
    on x86. The last related patch on Qemu side was merged after Xen4.20
    release. So mention this feature in Xen4.21 entry.
    
    But SR-IOV is not yet supported on PVH dom0, add a note for it.
