With CONFIG_DM_USB_GADGET=y, we no longer need any board_usb_*() logic
because:
* the dwc2 driver is DM compatible, and handles its own clock enabling
* the dwc3-meson-gxl glue drivers handles "force mode switching"
Remove all mach-meson gx & axg usb code and enable CONFIG_DM_USB_GADGET.
Note: Only configs having both CONFIG_USB_DWC3_MESON_GXL=y *and*
USB_GADGET_DWC2_OTG=y have been updated.
