davinci_nand chipselect/init cleanup
Update chipselect handling in davinci_nand.c so that it can handle 2 GByte chips the same way Linux does: as one device, even though it has two halves with independent chip selects. For such chips the "nand info" command reports: Device 0: 2x nand0, sector size 128 KiB Switch to use the default chipselect function unless the board really needs its own. The logic for the Sonata board moves out of the driver into board-specific code. (Which doesn't affect current build breakage if its NAND support is enabled...)
