ARM: dts: suniv: add device tree for PopStick v1.1

PopStick is a minimal Allwinner F1C200s dongle, with its USB controller
wired to a USB Type-A plug, a SD slot and a SPI NAND flash on board, and
an on-board CH340 USB-UART converted connected to F1C200s's UART0.

Add a device tree for it. As F1C200s is just F1C100s with a different
DRAM chip co-packaged, directly use F1C100s DTSI here.

This commit covers the v1.1 version of this board, which is now shipped.
v1.0 is some internal sample that have not been shipped at all.
