ARM: dts: imx7-colibri: clean-up usdhc1 and add sleep config
Adding no-1-8-v property to usdhc1 to disable +1.8V signaling (UHS-I) mode on SoM dtsi level. Clean up no-1-8-v from Aster carrier board dtsi, which is using defaults from SoM dtsi and is not UHS-I capable. A carrier board may have a MMC/SD card slot with a switchable power supply. Add a pinctrl sleep used when the card power is off to avoid backfeeding to the card and add the "sleep" pinctrl to the usdhc1 controller.
