Subject: [PATCH 1/4] arm64: dts: allwinner: h6: orangepi: Add CPU supply regulator

The original orangepi 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.
