Commit c66d039197e4 broke NAND for non-DT boot on all OMAP2 and OMAP3
boards using board_nand_init(). Following error is seen at boot

[    0.154998]  (null): Unsupported NAND ECC scheme selected

For OMAP2 and OMAP3 platforms, the ecc_opt parameter in platform data
must be set to OMAP_ECC_HAM1_CODE_HW to work properly.

Tested on omap3-beagle c4.

Thanks applying into fixes with Cc stable v3.12+.
