mtd: move & update nand_ecclayout structure (plus board changes)
nand_ecclayout is present in mtd.h at Linux. Move this structure to mtd.h to comply with Linux. Also, increase the ecc placement locations to 640 to suport device having writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone up to 640 bytes and consequently the maximum ecc placement locations have also gone up to 640. Changes from Prabhabkar's version (squashed into one patch to preserve bisectability): - Added _LARGE to MTD_MAX_*_ENTRIES This makes the names match current Linux source, and resolves a conflict between http://patchwork.ozlabs.org/patch/280488/ and http://patchwork.ozlabs.org/patch/284513/ The former was posted first and is closer to matching Linux, but unlike Linux it does not add _LARGE to the names. The second adds _LARGE to one of the names, and depends on it in a subsequent patch (http://patchwork.ozlabs.org/patch/284512/). - Made max oobfree/eccpos configurable, and used this on tricorder, alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build for me without doing so, due to a size increase). On tricorder SPL, this saves 2576 bytes (and makes the SPL build again) versus the new default of 640 eccpos and 32 oobfree, and saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.
