ppc4xx: Change Kilauea to use the common DDR2 init function
This patch changes the kilauea and kilauea_nand (for NAND booting) board port to not use a board specific DDR2 init routine anymore. Now the common code from cpu/ppc4xx is used. Thanks to Grant Erickson for all his basic work on this 405EX early bootup. Signed-off-by: Stefan Roese <sr@denx.de>
