sunxi: Add mk802_a10s board / defconfig

The mk802_a10s re-uses is the "classic" mk802 case and functionality, but has
an A10s SoC inside rather then the A10, it features 512M or 1G RAM, 4G nand,
a mini-hdmi female connector, USB-A receptacle, mini-usb receptacle (OTG)
and a sdio realtek wifi chip. Unlike the original mk802 it does have a pmic,
the axp152.
