[PATCH] ARM: imx6: dh-imx6: Enable USB OTG ID pin pull up in SPL

[Marek Vasut]

Enable SoC pull up for USB OTG ID pin in SPL. There is no dedicated pull up
resistor on the SoM itself, and the pull up is mandatory for correct USB OTG
ID pin detection. U-Boot proper already configures the USB OTG ID pin pull
up via DT pinctrl node entry.
