usb: musb: dsps: dt binding - add resources, example
OMAP2+ family of devices are now obtaining resources via DT, earlier it was obtained from hwmod. Update binding document accrodingly, while at it add example. Signed-off-by: Afzal Mohammed <afzal@ti.com> Reviewed-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Benoit Cousson <b-cousson@ti.com>
