[PATCHv2] i.MX6-SabreAuto: WEIM: add steering-gpios to set WEIM for NOR

[alison at she-devel.com]

From: Alison Chaiken <alison_chaiken at mentor.com>

The EIM switch of the i.MX6 SabreAuto CPU cards can connect pins
EIM_D18 and EIM_D30 of the CPU to either the parallel NOR or to other
peripherals.  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.
