The GICv2 and GICv3 version of the FVP DT files are unnecessarily split, as the common part of the peripherals is the same: it's literally just the interrupt controller node that is different. To facilitate a unification, refactor the DT include files to explicitly include a snippet with just the GICv3 description, and a generic base DT file for the rest. This generic file can then be reused by the GICv2 versions later. Since we can only have a /memreserve/ entry *before* any DT nodes, move that line to each file, to allow including the GIC DT file separately.
