arm64: dts: mediatek: mt8390-genio-common: Enable HDMI output

Browse Source 
Add a node for the HDMI-A connector found on this board, then
configure the display pipeline and enable the required DPI1
interface, HDMI controller, its integrated DDC and the HDMI
PHY to enable support for the HDMI output provided by these EVKs.
