[PATCH 3/4] dt-bindings: display: lcdif: Allow display0 child node for i.MX6UL

[Frank.Li at oss.nxp.com]

From: Frank Li <Frank.Li at nxp.com>

The legacy i.MX6UL LCDIF binding uses a display0 child node to describe
the attached display. Update the binding schema to allow this child node
for fsl,imx6ul-lcdif.

Fixes the following CHECK_DTBS warning:
  arch/arm/boot/dts/nxp/imx/imx6ul-tx6ul-0010.dtb: lcdif at 21c8000 (fsl,imx6ul-lcdif): 'disp0' does not match any of the regexes: '^pinctrl-[0-9]+$'

A follow-up patch renames the child node from disp0 to display0 to match
the updated binding.
