If CONFIG_NR_DRAM_BANKS is not defined, we say (for simplicity) that we have 1 bank, but for some boards should be interesting that we can define CONFIG_NR_DRAM_BANKS. To handle this possibility just define the number of DRAM banks if is not already defined. This is useful for some OMAP3 boards where the DRAM initialitzation is only at u-boot level.
