mtd: nand: Fix probe of Samsung NAND chips
commit cfe3fdadb16162327773ef01a575a32000b8c7f4 upstream.
Apparently, the check for a 6-byte ID string introduced by commit
426c457a3216fac74e3d44dd39729b0689f4c7ab ("mtd: nand: extend NAND flash
detection to new MLC chips") is NOT sufficient to determine whether or
not a Samsung chip uses their new MLC detection scheme or the old,
standard scheme. This adds a condition to check cell type.
