arm64: dts: juno: Describe the full GICv2m region
Juno's GICv2m implementation consists of four frames providing 32 interrupts each. Since it is possible to plug in enough PCIe endpoints to consume more than 32 MSIs, and the driver already has a bodge to handle multiple frames, let's expose the other three as well.
