The GIC in ZynqMP cover a 64K address space, however the actual registers are decoded within a 4K address space and mirrored at the 4K boundaries. This change fixes the defined size for these regions as it was set to 0x4000/16K incorrectly. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com> Reviewed-by: Edgar E.
