Subject: [PATCH v3 06/16] dt-bindings: lcdif: Do not require power-domains for i.MX6ULL

i.MX6UL(L) uses "fsl,imx6sx-lcdif" as fallback compatible string,
but has only very lightweight DISPLAY power domain. Its DISPLAY
power domain is not supported by the binding / Linux kernel at
the moment. Since the current setup is working, let's remove the
power-domain from being required for that platform to fix the warning
printed by CHECK_DTBS=y.

Fixes: f62678a77d58 ("dt-bindings: mxsfb: Document i.MX8M/i.MX6SX/i.MX6SL power-domains property")
Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
