davinci_nand, trivial : use symbolic ECC start command
The ECC calculations were started by writing 1 << 13 to the nand FCR register; that value is also defined as DAVINCI_NANDFCR_4BIT_CALC_START in emif_defs.h. This patch substitutes the macro DAVINCI_NANDFCR_4BIT_CALC_START for the magic number '1 << 13'.
