This patch moves some board specific NAND configs:
- FROM: generic config files like 'ti_armv7_common.h' and 'ti_am335x_common.h'
- TO: individual board config files using these configs.
So that each board can independently set the value as per its design.
Following configs are affected in this patch:
CONFIG_NAND_OMAP_GPMC:
CONFIG_NAND_OMAP_ELM:
CONFIG_SPL_NAND_AM33XX_BCH:
CONFIG_SYS_NAND_U_BOOT_OFFS:
CONFIG_CMD_SPL_NAND_OFS:
CONFIG_SYS_NAND_SPL_KERNEL_OFFS:
CONFIG_CMD_SPL_WRITE_SIZE:
This patch also updates documentation for few of above NAND configs.

On OMAP platforms, this CONFIG specifies NAND ECC scheme.
