[PATCH v3 1/5] riscv: dts: spacemit: k3: move USB3 phy to board level

[Aurelien Jarno]

On the SpacemiT K3 SoC, the combo phy provides 8 lines that can
either be used for PCIe or USB3, depending on its configuration
(spacemit,apmu). This configuration is defined at the board level, and
assigning a phy line to a USB3 controller while it is configured as PCIe
results in an "Invalid PHY mode" error.

Move the USB phy definitions at the board level, as it is done for the
submitted PCIe controller [1].
