This adds the bindings, for the mediatek ISP3.0 SENINF module embedded in
some Mediatek SoC, such as the mt8365

+description:
+  The ISP3.0 SENINF is the CSI-2 and parallel camera sensor interface found in
+  multiple MediaTek SoCs. It can support up to three physical CSI-2
+  input ports, configured in DPHY (2 or 4 data lanes) or CPHY depending on the soc.
+  On the output side, SENINF can be connected either to CAMSV instance or
+  to the internal ISP. CAMSV is used to bypass the internal ISP processing
+  in order to connect either an external ISP, or a sensor (RAW, YUV).
