Subject: [PATCH] dt-bindings: display: mediatek: dpi: add power-domains
 example

DPI is part of the display / multimedia block in MediaTek SoCs, and
always have a power-domain (at least in the upstream device-trees).
Add the power-domains property to the binding example.

Fixes: 9273cf7d3942 ("dt-bindings: display: mediatek: convert the dpi bindings to yaml")
