[PATCH V9 20/24] arm64: dts: allwinner: h616: add display engine, bus and mixer nodes

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

The Allwinner H616 and variants (H618, H700 and T507) have a new display
engine variant (DE33). Support has been added to the existing DE2/DE3
sun4i driver in a previous patch series (x). The variant is selected via
the appropriate mixer device tree compatible string.

Add the respective device-tree nodes for the DE, bus, clock and mixer to
the H616 DTSI, and the matching SRAM section for the DE.
