reserved pins w/ 2.54mm pitch. The board can use either SoChip S3 or
Allwinner V3L SoCs.

Add the device tree binding of the basic version of the core board --
w/o eMMC or SPI Flash, w/ TF slot or WSON8 SD, and use S3 SoC.

No changes since v3.

Patch introduced in v2.

If the S3 is just a rebranded V3, then we should have the v3 compatile
in that list too.

S3 is V3 with copackaged DDR3 DRAM.

It's pin incompatible w/ V3.
