From: Aviram Dali <aviramd at marvell.com>

A missing layouts were added to the driver to support NAND flashes
with ECC layouts of 12 or 16 with page sized of 2048, 4096 or 8192.

Usually theses are rare layouts, but in Marvell AC5 driver, the ECC
level is set according to the spare area, so we may use these layouts
more frequently.
