Adds support to use ELM as BCH 4 & 8 bit error correction module and adds support for single shot read_page and write_page functions Platforms containing the ELM module can be used to correct errors reported by BCH 4, 8 & 16 bit ECC scheme. For now only 4 & 8 bit support is added. BCH 4 & 8 bit error detection support is already available in mainline kernel and works with software error correction. This series is based on top of [1] &[2] 1. linux-next/master 2. linux-omap-dt/for_3.7/dts_part2 Nand driver tested for BCH 4 & 8 bit error correction per sector. This being tested by introducing bit errors at multiple sectors inside page.
