[U-Boot] [PATCH] arm/omap3: limit chip select iteration based on board config

[Grant Erickson]

Only attempt to configure and add DRAM at chip select 1 if the board has configured more than one bank of DRAM.

This prevents boards that have CONFIG_NR_DRAM_BANKS set to 1 from getting an incorrect DRAM size.
