The mt8188 SoC provides an HDMI encoder and PHY fed through the DPI1 interface attached to the vdosys1 display data path.
Add the U-Boot specific bits to mt8390-genio-common-u-boot.dtsi: - a "memory-region" phandle on the hdmi node pointing at the framebuffer reserved-memory region; - aliases for the pipeline resources that have no upstream alias (the vdosys1 syscon and the larb2/larb3 SMI larbs), which the video driver resolves directly since U-Boot has no DRM framework to walk the graph.
