The EHCI and OHCI devices are created and registered by the omap-usb-host driver, and if no driver is present yet to handle them they will patiently wait for they turn without any adverse effect. This mechanism is thus not needed, remove it. This fixes a bug that prevents EHCI and OHCI devices from being probed on the Pandaboard since commit 84badc5ec5fc ("ARM: dts: omap4: Move l4 child devices to probe them with ti-sysc"), as then omap-usb-host devices are now registered after the omap-usb-host driver initializes, and thus fail to probe due to platform_driver_probe() not finding any device.
