This patch merges the BCH ECC algorithm from the 3.0 Linux kernel.
This enables U-Boot to support modern NAND flash chips that
require more than 1-bit of ECC in software.

This change follows the change by Wolfgang Grandegger (commit 6c869637fef),
which allows to remove useless NAND_MAX_CHIPS definitions in board config
files.

nand_spl_simple: store ecc data on the stack
Currently nand_spl_simple puts it's temp data at 0x10000 offset in SDRAM
which is likely to contain already loaded data.
The patch saves the oob data and the ecc on the stack replacing
the fixed address in RAM.
