board-mityomapl138.c - only one board file with NAND_BUSWIDTH_16 option set in pdata.
By default bus width is treated as 8 bit, in another case we have to set it.
Currently bus width setup is done in davinci_aemif_setup(). So, to set bus width
correctly we have to call davinci_aemif_setup() for board in question.
