ppc4xx: Kilauea: Fix SDRAM init in NAND booting version
DDR2 Auto-calibration needs to be disabled on the NAND booting PPC4xx targets. Otherwise the configured fixed init values for some DDR2 controller registers (e.g. RQDC) are not initialized at all resulting in a non working SDRAM. Signed-off-by: Stefan Roese <sr@denx.de>
