Add a steering-gpios property to the imx6qdl-sabreauto device-tree to allow boot-time configuration of the EIM. Use GPIO5, pin 4 to connect EIM_D18 to the NOR so the do_map_probe() function correctly detects the CFI. Support is not added for boot-time steering of EIM_D30 due to present inability to test.
