omap: Don't enable GPMC CS0 with nothing attached

Browse Source 
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.
