lcdif nodes are differ wrt specific LCD connected on Is.IoT MX6UL
module, so create separate file 'imx6ul-isiot-common.dtsi' for common
lcdif node structure and include the same on respective dts.
More common nodes will add in future patches.

May be I can use stmpe811@41 the existing imx6qdl-apalis.dtsi using
the similar notation.

Actually this is interrupt pad, for the touch controller via stmpe so
I can rename pinctrl_touch_int.

stmpe_touchscreen {
This is also compatible with existing dtsi files

Per application notes of stmpe811 below, I would suggest you name it
gpio-expander.

Just to understand, why codec: sgtl5000@0a not a suitable notation?
couldn't see any Documentation.
