mtd: rawnand: omap: Use ECC information from the generic structures
As part of a previous fix, we imported the BCH internal structure in
order to get information about the BCH engine configuration.
It is best not to access private structure so instead, a small rework
has been done to export more information from the ECC engines. Now,
let's use these.
