When SPL_NAND_SUNXI option is selected in config, set some configuration options for sunxi NAND.
This commit also introduces the configurable options in Kconfig.

Changes in v3: - added new options in Kconfig to support different chips - changed descriptions to comply with patman rules
Changes in v2: - removed traces of non-SPL specific code - renamed defines to be more relevant - moved Kconfig entry for the driver to drivers/mtd/nand - reworded Kconfig entry help
