Most of the usb-controller init code found in ehci-sunxi.c also is necessary to init the otg usb controller, so move it to a common place. While at it also update various #ifdefs / defines for sun8i support. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
