Subject: [PATCH 11/14] usb: otg: Enable probing of the ab8500 during a Device Tree boot

Without this patch, if Device Tree is enabled the AB8500 USB OTG driver
wouldn't get probed at all, as there is no reference to it from platform
code. This patch ensures the driver is probed during normal DT start-up.
