[U-Boot] [PATCH] ppc4xx: Kilauea: Fix SDRAM init in NAND booting version

[Stefan Roese]

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.
