The Radxa Rock 2 Square board is a combination of the Radxa Rock 2 SoM
with the Square baseboard. Add a dtsi for the SoM which can be included
into the dts for the various baseboards (e.g. full and square) and a dts
for the square board.
Currently supported are serial console, wired networking, hdmi output,
eMMC and SD storage and USB.

Changes in v2:
- Use gpio bank numbers directly instead RK_GPIO<number>
- Use radxa,rock2-square as compatibility string and document it in
rockchip.txt
- Fix ordering in memory node
- Don't add broken-cd in the emmc node, unneeded as non-removable is set
- coding-style fixes (double empty lines, comment style)
- Removed redundant status properity in the act8846 node
- Use emmc reset power-sequence to ensure proper MMC card reset
