[PATCH 2/4] arm64: dts: allwinner: h6: pine: Add CPU supply regulator

[Yangtao Li]

The original pine use the dcdca to supply the CPU cores. According
to the axp805 spec, the range of dcdca is 0.6 to 1.1v, 1.12 to 1.52v.
In order to support more CPU frequency, slightly increase the voltage
maximum and minimum.
