sunxi: Add INITIAL_USB_SCAN_DELAY Kconfig option
Some boards have on board usb devices which need longer than the USB spec's 1 second to connect from board powerup. Add a config option which when non 0 adds an extra delay before the first usb bus scan. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
