riscv: dts: spacemit: Enable USB3.0 on BananaPi-F3

Browse Source 
Enable the DWC3 USB 3.0 controller and its associated usbphy2 on the
Banana Pi F3 board.

The board utilizes a VLI VL817 hub, which requires two separate power
supplies: one VBUS and one for hub itself. Add two GPIO-controlled
fixed-regulators to manage this.
