Subject: [PATCH V2] ARM: dts: imx6q-logicpd: Enable ili2117a Touchscreen

The LCD used with the imx6q-logicpd board has an integrated
ili2117a touch controller connected to i2c1.

This patch adds the node to enable this feature.

ili2117 support is scheduled to be introduced for Kernel v5.5.

V2:  Change node to touchscreen@26 and move comment about 5.5 to under the dashes
