Return the same clock for usbh and usbd on BCM6318 to prevent the clock
getting disabled despite being supposed to be enabled, e.g. by the
following sequence:
clk_enable(usbh); <- usbh->usage = 1, enabled
clk_enable(usbd); <- usbd->usage = 1, enabled (no effect)
clk_disable(usbd); <- usbd->usage = 0, -> disabled!
