Boris Brezillon 872164e41f mtd: nand: sunxi: prefer 1k ECC blocks when applicable 
Switching to 1k ECC blocks when possible provides better resistance against
concentrated bitflips. Say you have those two configurations:

1/ 16bits/512bytes
2/ 32bits/1024bytes

Both of them require the same amount of ECC bytes (only true for this
specific engine), but the second config allows you to correct the case
where most of your bitflips are concentrated in a single 512bytes portion.

This fact makes the 1k ECC block size more advantageous than the 512bytes
one.
