[PATCH 2/2] mtd mxc_nand: move ecc strengh setup before nand_scan_tail

[s.hauer@pengutronix.de (Sascha Hauer)]

Since this commit:

  commit 6a918bade9dab40aaef80559bd1169c69e8d69cb

     mtd: flash drivers set ecc strength

The mxc_nand driver fails with:

Driver must set ecc.strength when using hardware ECC

This is because nand_scan_tail checks for correct ecc strength
settings, so we must set them up before nand_scan_tail.
