[U-Boot] [PATCH] imx: Select the pinctrl drivers when DM is used

[Fabio Estevam]

When using device model it is required to select the pinctrl
drivers so that the pins can be properly configured via
devicetree.

mx6sabreauto board is an example of a target that uses DM and does
not select the pinctrl drivers.

Instead of doing the pinctrl driver selection in each individual
defconfig file, select it at SoC level when DM is used.

Unfortunately, after some testing it turned out that this patch causes
build break for "display5_factory_defconfig"

The build break is as follows:
