sunxi: board: Splitting CHIP defconfig for nand.

This patch split CHIP defconfig to add nand 4G and 8G support.

Some CONFIG was put at the end of defconfig to ease comparison between:
- CHIP Pro
- CHIP with Toshiba 4G
- CHIP with Hynix 8G

Witch are essentialy the same board with differents nand and memory.

Values was taken from now defunct compagny script "chip-update-firmware.sh"

Mmh, I am puzzled how this is supposed to work? I thought that the NAND
in the non-Pro version was not supported (MLC?). So booting via USB was
the only option?
Has this changed?

Can someone confirm that this works?

Cheers,
Andre

The CHIP-Pro is indeed different, it's using a different SoC and NAND
(SLC) chip.

All the variants of the CHIP use an MLC NAND that isn't supported at all
by U-Boot.

I would discourage you from merging any MLC NAND related patch until
some form of MLC support is merged into U-Boot.
