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.

For testing, the following kernel configurations should be enabled:

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

This series is based on the spacemit k1/for-next branch.
