mtd: nand: omap: fix ecclayout->oobfree->offset
1) In current implementation, ecclayout->oobfree->offset is calculated with
respect to ecclayout->eccpos[0] which is incorrect because ECC bytes may not
be stored contiguously in OOB.
So, this patch calculates ecclayout->oobfree->offset with respect to last
ECC byte-position 'eccpos[ecclayout->eccbytes-1]'.
2) ECC layout of some ecc-schemes expects reserved-markers at specific eccpos[]
which should not be over-written by any file-system metadata.
So this patch aligns oobfree->offset taking into account of such markers.
