[PATCH v2 03/12] hw/misc/allwinner-dramc: Move sysbus_mmio_map call from init -> realize

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

In order to make the next commit trivial, move the sysbus_init_mmio()
call in allwinner_r40_dramc_init() just before the corresponding
sysbus_mmio_map_overlap() call in allwinner_r40_dramc_realize().
