[PATCH v3 07/13] ARM: dts: sunxi: Use label to reference pio in sunxi-common-regulators

[wens@csie.org (Chen-Yu Tsai)]

Use the label to reference the pin controller node, so that we can use
sunxi-common-regulators with sunxi families that don't share the same
address space mappings, such as sun9i.

This patch is mostly space changes due to the reduction of node parents.
