arm: dts: dra76-evm: Add CAL and OV490 nodes

Add device nodes for CSI2 camera board OV490 and the GPIO expander on
the adapter board.

Add board mux entries to set the i2c clk, board muxes, etc. Also add
the endpoint nodes describing the CSI2 PHY configuration.

Add CAL port nodes and link endpoint with the ov490 node.
