arm64: dts: mediatek: Add smi_common node for MT8183

The SMI (Smart Multimedia Interface) Common is a bridge between the m4u
(Multimedia Memory Management Unit) and the Multimedia HW. This block is
needed to support different multimedia features, like display, video
decode, and camera. Also is needed to control the power domains of such
HW blocks.
