at91: remove MTD_NAND_ATMEL_BUSWIDTH_16 option
no board configure it as 'n' and it's an issue to merge all defconfigs in one On AT91SAM926x boards both types of NAND flash can be present (8 and 16 bit data bus width). so will pass it via system_rev Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: Patrice Vilchez <patrice.vilchez@atmel.com>
