[PATCH v2 2/3] ARM: dts: sunxi: add support for Orange Pi Zero board

[Icenowy Zheng]

Orange Pi Zero is a board that came with the new Allwinner H2+ SoC.

Add a device tree file for it.

Changes since v2:
- Use generic pinconf binding instead of legacy allwinner pinctrl binding.
- removed uart3, which is not accessible on Orange Pi Zero.
- Removed sun8i-h2plus.dtsi and make Orange Pi Zero dts directly include
  sun8i-h3.dtsi.
- Removed allwinner,sun8i-h3 compatible.
