xen_arm: Create virtio-mmio devices during initialization
In order to use virtio backends we need to allocate virtio-mmio parameters (irq and base) and register corresponding buses. Use the constants defined in public header arch-arm.h to be aligned with the toolstack. So the number of current supported virtio-mmio devices is 10. For the interrupts triggering use already existing on Arm device-model hypercall. The toolstack should then insert the same amount of device nodes into guest device-tree.
