[PATCH v2 07/10] usb: dwc3: generic: add board_usb_init/cleanup hooks

[Peng Fan (OSS)]

From: Ye Li <ye.li at nxp.com>

Call board_usb_init() during dwc3_generic_probe() and
board_usb_cleanup() during dwc3_generic_remove() to allow
board-level USB configuration (e.g. Type-C CC role, SS mux,
VBUS control) before DWC3 core initialization.
