[PATCH v3 3/4] dt-bindings: display: lcdif: Allow display0 child node for i.MX6UL

[Frank.Li@oss.nxp.com]

From: Frank Li <Frank.Li@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@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.

sashiko report problem and allow dma/dma-names for i.MX6ul. which should
be fine for this kinds of old platform.

Ideally it should use port. but platform is too old to avoid break back
compatiblity and leave as it. Needn't complex if-else branch.
