omap: Don't enable GPMC CS0 with nothing attached
If CONFIG_(NAND|NOR|ONENAND) is not defined, no configuration is set
for GPMC on chip select #0---size is 0. In this case, the GPMC
configuration should be reset but not enabled. Enabling causes the
Gumstix DuoVero board to hang when entering Linux.
