omap: gpmc: 'nandecc sw' can use HAM1 or BCH8
The 'nandecc sw' command selects a software-based error correction algorithm. By default, this is OMAP_ECC_HAM1_CODE_SW but some platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their software-based correction algorithm. Allow a user to be specific e.g. # nandecc sw <hamming|bch8> where 'hamming' is still the default. Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set to a hardware-based ECC scheme---a little strange when the user has requested 'sw' ECC.
