PATCH v6 3/3 riscv: dts: spacemit: Enable USB3.0/PCIe on OrangePi RV2

In reply to Han Gao

Enable the DWC3 USB 3.0 controller and its associated usbphy2 on the OrangePi RV2 board.

The board utilizes a Genesys Logic GL3523 USB3.0 hub.

Define a 3.3v fixed voltage regulator for PCIe and enable PCIe and PHY-related Device Tree nodes for the OrangePi RV2.
