Subject: [PATCH] bords: 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.
