arm64: dts: imx8mp-kontron: Fix touch reset configuration on DL devices

Browse source

The reset signal needs a pullup, but there is no hardware pullup.
As a workaround, enable the internal pullup to fix the touchscreen.

As this deviates from the default generic GPIO settings in the OSM
devicetree, add a new node for the touch pinctrl and redefine the
generic gpio1 pinctrl.
