mtd: move & update nand_ecclayout structure (plus board changes)

Browse Source 
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.
