these variables are curently defined in several config files but the driver doesn't use them and defaults to hardcoded values in nand_defs.h It's interesting to be able to change this hardcoded valude when the hardware is not using the default adress signals to drive ALE and CLE and two configuration defines already exist for this purpose so use them.
