ARM: OMAP2+: nand: Fix NAND on OMAP2 and OMAP3 boards

Commit c66d0391 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.

Fixes: c66d0391 (mtd: nand: omap: combine different flavours of 1-bit hamming ecc schemes)
