phy: meson-gxl: remove invalid USB3 PHY driver

The registers which are managed by the meson-gxl-usb3 PHY driver are
actually "USB control" registers (which are "glue" registers which
manage OTG detection and routing of the OTG capable port between the
DWC2 peripheral-only controller and the DWC3 host-only controller).

Drop the meson-gxl-usb3 PHY driver now that the dwc3-meson-gxl-usb
driver supports the USB control registers on GXL and GXM SoCs (these
were previously managed by the meson-gxl-usb3 PHY driver).
