[PATCH 2/3][v2] nand_base: use nand_ooblayout_lp_hamming_ops for 1bit hamming as default

[Alexander Couzens]

commit 41b207a70d3a ("mtd: nand: implement the default mtd_ooblayout_ops")
uses a different ooblayout for platforms which doesn't set the
layout by itself. Use for 1bit hamming the old layout.
