powerpc/mpc85xx:NAND_SPL:Avoid IFC/eLBC Base address setting 

During NAND_SPL boot, base address and different register are programmed
default by corresponding NAND controllers(eLBC/IFC). These settings are
sufficient enough for NAND SPL.

Avoid updating these register.They will be programmed during NAND RAMBOOT.
