At the moment we use 2 IO devices per GICv3 redistributor: one one for the RD_base frame and one for the SGI_base frame. Instead we can use a single IO device per redistributor (the 2 frames are contiguous). This saves slots on the KVM_MMIO_BUS which is currently limited to NR_IOBUS_DEVS (1000). This change allows to instantiate up to 512 redistributors and may speed the guest boot with a large number of VCPUs.
