[Qemu-arm] [PATCH v7 15/20] hw/arm/sysbus-fdt: Pass the VirtMachineState to the node creation functions

[Eric Auger <eric.auger@redhat.com>]

The VirtMachineState contains some dt phandles that will be used
in some node creation functions. For instance we plan to use the
PCI host controller phandle in the smmu node creation function. So
let's pass the VirtMachineState handle down to the node creation
functions by enhancing the involved datatypes.
