Roger Quadros 7d5929c1f3 mtd: nand: omap: Revert to using software ECC by default 
For v3.12 and prior, 1-bit Hamming code ECC via software was the
default choice. Commit c66d039197 in v3.13 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.

This ECC layout change causes NAND filesystems created in v3.12
and prior to be unusable in v3.13 and later. So revert back to
using software ECC by default if an ECC scheme is not explicitely
specified.

This defect can be observed on the following boards during legacy boot
