[PATCH v1 05/25] arm64: dts: colibri-imx8x: Add atmel pinctrl groups

[Philippe Schenker <dev@pschenker.ch>]

From: Philippe Schenker <philippe.schenker@toradex.com>

Add pinctrl groups for enabling atmel touchscreen support.
Remove the pads out of pinctrl_hog0 as they now can be enabled more
specific using pinctrl_atmel_conn label.
