sunxi: move the NAND parameters to Kconfig

Move the NAND parameters from defconfig files to Kconfig for SUNXI
architecture only. Fort now only the CHIP pro is migrated.

It would have been better to convert this defconfig entry to Kconfig for
all supported machines/architectures but it has been abandoned due to a
fairly high amount of errors reported by the moveconfig.py tool. This is
due to defines quite often being multiplications of values/other defines
not correctly handled.
