Revert "mtd: rawnand: marvell: fix layouts"

[ Upstream commit fbd72cb463fdea3a0c900dd5d6e813cdebc3a73c ]

This reverts commit e6a30d0c48a1e8a68f1cc413bee65302ab03ddfb.

This change resulted in the 8bit ECC layouts having the incorrect amount
of read/write chunks, the last spare bytes chunk would always be missed.
