ENGR00213293 : Enable WEIM NOR support on the imx6 ARD revb quad/solo.

Added IOMUX,GPIO and early param support for the parallel nor to work
on the imx6 revB quad/solo. Since the parallel NOR can clash with I2C3,
and SPI, an early param was added to enable WEIM NOR chips using boot
args.

The Weim NOR needs a HW rework for it to work. This rework is going
to disable the SPI NOR. Modified files:
