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
