[PATCH v3 07/18] arm64: dts: allwinner: a64: Add tcon1 HDMI pipeline

[Icenowy Zheng]

>HDMI on Allwinner A64 similar behaviour like H3 with
>PHY of two clock parents (pll-0, pll-1) connected via
>second mixer and tcon.
>
>Add all require entries needed for HDMI to function.

>Note, that Figure 3-3.Module Clock Diagram also showing

>it in future once we have mixer0 pipeline.

>Changes for v3:
>- Squash all pipeline components in one patch
>- Add status for mixer1 and tcon1
>Changes for v2:
>- Change compatibles and other based on previous patch changes
