pinctrl: add pinctrl driver for imx6dl

The imx6dl is a derivative of imx6q with very limited difference.  These
two SoCs are so compatible that they can be handled as one platform in
software.  That said, we will not have target SOC_IMX6DL but just
reusing SOC_IMX6Q.   That's why the pinctrl-imx6dl driver is added here
with symbol PINCTRL_IMX6Q controlling the build of it.

* Freescale IMX6 DualLite/Solo IOMUX Controller
Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
and usage.
Required properties:
- compatible: "fsl,imx6dl-iomuxc"
- fsl,pins: two integers array, represents a group of pins mux and config
setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
pin working on a specific function, CONFIG is the pad setting value like
pull-up for this pin. Please refer to imx6dl datasheet for the valid pad
config settings.
