Add the QSPI controller node and describe the attached SPI NOR flash
(Winbond W25Q64FWSSAQ).
Add a corresponding vendor flash partition layout.

Enable the DWC3 USB 3.0 controller, its associated combo_phy (USB 3 PHY)
and usbphy2 (USB 2 PHY) on the MusePi Pro board.
The board uses a VLI VL817 hub, providing four ports.
