sunxi: add V3/S3 support

Allwinner V3/Sochip S3 uses the same die with Allwinner V3s/S3L, but V3 comes
with no co-packaged DDR (DDR3 is usually used externally), and S3L comes
with co-packaged DDR3.

Add support for Allwinner V3/S3 chips by add SoC names to original V3s
choice, and allow to select DDR3.
