Subject: [PATCH 0/3] riscv: dts: spacemit: Add USB 3.0 support for K1

This patch series enables the DWC3 USB 3.0 host controller on the
Spacemit K1 SoC, and enables it for the Banana Pi F3 board.

To make USB 3.0 work on the K1, we need patches for the USB2 PHY [1],
ComboPHY [2], and DWC3 [3] driver, also, ensure enabling the following
configurations:

CONFIG_PHY_SPACEMIT_K1_USB2=y
CONFIG_PHY_SPACEMIT_K1_PCIE=y
CONFIG_USB_DWC3=y
CONFIG_USB_ONBOARD_DEV=y

The series is based on v6.18-rc1.
