GIC generally uses a 4k memory region for the various subregions, such
as GICC, GICD, GICV and GICH. Macroify this number in the publicly
visible header.
Some machine model code may need to know the individual subregion size
to implement special addresses mappings (such as aliases and
under-decoding logic).
