riscv: dts: spacemit: enable USB 3 ports on Milk-V Jupiter

Enable the DWC3 USB 3.0 controller (USB#2 port in the K1 datasheet) and
its associated combo_phy (USB 3 PHY) and usbphy2 (USB 2 PHY) on the
Milk-V Jupiter board.

The board uses a VLI VL817 hub, providing four ports. Two are routed to
the 3.0 type-A connectors, and two to the F_USB3 front USB header. The
hub requires two separate 5V power supplies: one for the hub itself and
one for the USB connectors. Add an always-on regulator sourcing 5V from
the DC-IN input, along with two GPIO-controlled fixed regulators to
manage the hub and connectors power supplies.

Note that the board also provides four USB 2.0 ports (two via type-A
connectors and two via the F_USB2 front USB header), but these are
handled by a different controller (USB#1 port in the K1 datasheet).
