davinci_nand: cleanup I (minor)
Minor cleanup for DaVinci NAND code: - Use I/O addresses from nand_chip; CONFIG_SYS_NAND_BASE won't be defined when there are multiple chipselect lines in use (as with common 2 GByte chips). - Cleanup handling of EMIF control registers * Only need one pointer pointing to them * Remove incorrect and unused struct supersetting them - Use the standard waitfunc; we don't need a custom version - Partial legacy cleanup: * Don't initialize every board like it's a DM6446 EVM * #ifdef a bit more code for BROKEN_ECC Sanity checked with small page NAND on dm355 and dm6446 EVMs; and large page on dm355 EVM (packaged as two devices, not one).
