[PATCH 4/4] imx: add PCI fixup for PEX860X on Gateworks board

[Tim Harvey]

The PEX860X has GPIO's which are used for PCI Reset lines on the
Gateworks Ventana boards.  The GPIO's need to be set as output
level high so as to allow the PCIe devices to come out of reset.

Sorted it like 51xx, 52xx, 53xx, 54xx, and applied the patch.  Thanks.
