Subject: [PATCH 06/18] dt-bindings: display: mediatek: dpi: add
 power-domains property

From: Fabien Parent <fparent@...libre.com>

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 documentation.
