[9/9] arm64: dts: mediatek: mt8186: Add display nodes
Commit Message
Add display nodes and GCE info for MT8186 SoC. Also, add GCE
(Global Command Engine) properties to the display nodes in order to
enable the usage of the CMDQ (Command Queue), which is required for
operating the display.

If there's only one instance, you could drop the trailing zero. Same
for all the other nodes.

the display driver doesn't properly detect the second pipeline, and only
one CRTC is generated.
