    hw/arm/virt: Rename default_bus_bypass_iommu
    
    Since commit d8fb7d0969d5 ("vl: switch -M parsing to keyval"), machine
    parameter definitions cannot use underscores, because keyval_dashify()
    transforms them to dashes and the parser doesn't find the parameter.
    
    This affects option default_bus_bypass_iommu which was introduced in the
    same release:
    
    $ qemu-system-aarch64 -M virt,default_bus_bypass_iommu=on
    qemu-system-aarch64: Property 'virt-6.1-machine.default-bus-bypass-iommu' 
not found
    
    Rename the parameter to "default-bus-bypass-iommu". Passing
    "default_bus_bypass_iommu" is still valid since the underscore are
    transformed automatically.
    
    Fixes: 6d7a85483a06 ("hw/arm/virt: Add default_bus_bypass_iommu machine 
option")
