Convert CONFIG_NAND_OMAP_GPMC et al and CONFIG_NAND_MXC to Kconfig
This converts the following to Kconfig:
CONFIG_NAND_MXC
CONFIG_NAND_OMAP_GPMC
CONFIG_NAND_OMAP_GPMC_PREFETCH
CONFIG_NAND_OMAP_ELM
CONFIG_SPL_NAND_AM33XX_BCH
CONFIG_SPL_NAND_SIMPLE
CONFIG_SYS_NAND_BUSWIDTH_16BIT

[trini: Finish migration of CONFIG_SPL_NAND_SIMPLE, fix some build issues,
add CONFIG_NAND_MXC so we can do CONFIG_SYS_NAND_BUSWIDTH_16BIT]
