[PATCH v4 07/21] ARM: dts: imx7-colibri: fix 1.8V/UHS support

From: Stefan Agner <stefan.agner@toradex.com>

Add pinmuxing and do not specify voltage restrictions for the usdhc
instance available on the modules edge connector. This allows to use
SD-cards with higher transfer modes if supported by the carrier board.
