[PATCH] ARM: dts: sun6i: Convert hummingbird a31 dts to label references

[Chen-Yu Tsai]

Using label references is preferred when override settings from the
included dtsi.

My AXP221 series touches this file. I thought I'd convert it first.

This looks like a lot of changes. But if you filter out all the
indentation changes, it's just the opening lines for each node.
