[PATCH 5/7] arm64: dts: allwinner: sun50i-h6: Add missing SRAM region for video engine

The SRAM C region contains a partial alias to the VE SRAM already
referenced by the video engine. To avoid access through this alias
window, the region should also be claimed by the video engine.

Add a reference to the SRAM C region to the video engine node.
