Subject: [PATCH v7 02/13] dt-bindings: display: mediatek: Add mmsys binding description

From: Matthias Brugger <mbrugger@suse.com>

The MediaTek DRM has a block called mmsys, which sets
the routing and enables the different blocks.
This patch adds one line for the mmsys bindings description and changes
the mmsys description to use the generic form of referring to a specific
Soc.

Signed-off-by: Matthias Brugger <mbrugger@suse.com>
