[PATCH 3/7] riscv: dts: spacemit: Define the P1 PMIC regulators for OrangePi RV2

[Han Gao]

Define the SpacemiT P1 PMIC voltage regulators and their constraints.

The power management hardware design on the OrangePi RV2 is identical to
the Banana Pi BPI-F3, so the DT Nodes were taken from k1-bananapi-f3.dts.
