boards: renesas: dts: Add overlay files to support LCDC

In order to avoid defining almost the same overlays for different sample codes and/or applications a common overlay file per display interface is defined under the boards dts folder. In doing so, an application/sample code will only have to define another overlay explicitly under application's board folder if more blocks are to be enabled. In either case, users should explicitly invoke the requested overfiles at 'west build' invokation by using the DTC_OVERLAY_FILE system variable. Signed-off-by: Ioannis Karachalios <[email protected]>
